href="/wiki/Programming_language" title="Programming language">programming language</a> running on the <a href="/wiki/Elektronika" title="Elektronika">Elektronika</a> <a href="/wiki/Elektronika_BK-0010" class="mw-redirect" title="Elektronika BK-0010">BK-0010-01/BK-0011M</a> and <a href="/wiki/UKNC" title="UKNC">UKNC</a> computers. It was developed at <a href="/wiki/Vilnius_University" title="Vilnius University">Vilnius University</a>, located in <a href="/wiki/Lithuania" title="Lithuania">Lithuania</a> which was a republic of the <a href="/wiki/Soviet_Union" title="Soviet Union">Soviet Union</a> at the time. </p><p>In contrast to most <a href="/wiki/Microcomputer" title="Microcomputer">microcomputer</a> dialects of BASIC of the era, which were <a href="/wiki/BASIC_interpreter" title="BASIC interpreter">interpreters</a>, Vilnius BASIC was a <a href="/wiki/Compile_and_go" class="mw-redirect" title="Compile and go">compile and go</a> language that compiled the source when the user entered the <code>RUN</code> command. It was otherwise similar to <a href="/wiki/GW-BASIC" title="GW-BASIC">GW-BASIC</a> and <a href="/wiki/MSX_BASIC" title="MSX BASIC">MSX BASIC</a> in style and most features, although it lacked some of the multimedia commands found in MSX. One oddity was that it did not allow more than one statement on a single line, a feature normally implemented using the colon. It also lacked the ability to open more than one data file at a time. </p><p>Only the UKNC version had a <a href="/wiki/Full_screen_editor" class="mw-redirect" title="Full screen editor">full-screen editor</a>, versions of the 0010 series machines used a <a href="/wiki/Line_editor" title="Line editor">line editor</a>. <a href="/wiki/Machine-dependent_software" title="Machine-dependent software">Machine-dependent</a> features, like graphics operators, parameters, and <code><a href="/wiki/PEEK_and_POKE" title="PEEK and POKE">PEEK/POKE</a></code> addresses were also different among the machines. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Description">Description</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Vilnius_BASIC&action=edit&section=1" title="Edit section: Description"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="mw-heading mw-heading3"><h3 id="Program_editing">Program editing</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Vilnius_BASIC&action=edit&section=2" title="Edit section: Program editing"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>In contrast to most BASIC dialects of the era, Vilnius BASIC was a <a href="/wiki/Compile_and_go" class="mw-redirect" title="Compile and go">compile and go</a> system, not an <a href="/wiki/BASIC_interpreter" title="BASIC interpreter">interpreter</a>. When the user types <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">RUN</code>, the compiler reads the code and produces a <a href="/wiki/Threaded_code" title="Threaded code">threaded code</a> executable that it then ran. Nevertheless, this detail was largely invisible to the user, as the system still allowed statements to be typed in without a line number for <a href="/wiki/Direct_mode" title="Direct mode">direct (immediate) mode</a>, or with a number for indirect mode in which case the new line was added to the program or replaced the same-numbered line if it already existed. </p><p>By the late 1970s, most microcomputer dialects offered a full-screen editor, in which the user can use the <a href="/wiki/Cursor_keys" class="mw-redirect" title="Cursor keys">cursor keys</a> to move around the program and type changes into any visible line of code. The Electronica systems were emulating an <a href="/wiki/PDP-11" title="PDP-11">PDP-11</a>, machines that had been built in the era before cursor-addressable <a href="/wiki/Computer_terminal" title="Computer terminal">computer terminals</a> were widely available and thus retain the older <a href="/wiki/Line_editor" title="Line editor">line editor</a> style. In these systems, a prompt is displayed that allows the user to type in one line of code, or recall a previously typed line and then edit it in-place. </p> <div class="mw-heading mw-heading3"><h3 id="Commands_and_statements">Commands and statements</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Vilnius_BASIC&action=edit&section=3" title="Edit section: Commands and statements"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The list of keywords supported in Vilnius can be separated into two groups, those that can only be used in direct mode, and those that can be direct or indirect. </p><p>The former, known as commands, included the common <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">CONT, LIST, NEW, RUN</code>. <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">CLOAD and CSAVE</code> load and save programs to <a href="/wiki/Cassette_tape" title="Cassette tape">cassette tape</a>. <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">AUTO</code> turned on automatic line number entry, <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">RENUM</code> renumbered the lines in the current program, and <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">DELETE</code> deleted ranges of lines using the same "to" format as LIST, for instance, <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">DELETE -200</code> would delete everything from the start of the program up to an including line 200. </p><p>Vilnius' primitives were similar to other BASICs of the era, and supported most of the elementary statements like <style data-mw-deduplicate="TemplateStyles:r886049734">.mw-parser-output .monospaced{font-family:monospace,monospace}</style><span class="monospaced">DATA, DEF FN, DIM, END, <a href="/wiki/For_loop" title="For loop">FOR..TO..STEP..NEXT</a>, <a href="/wiki/GOSUB" class="mw-redirect" title="GOSUB">GOSUB</a>, <a href="/wiki/GOTO" class="mw-redirect" title="GOTO">GOTO</a>, <a href="/wiki/Conditional_(programming)" class="mw-redirect" title="Conditional (programming)">IF..THEN</a> with an optional ELSE, INPUT, (optional) LET, LIST, PRINT, ON...GOTO and ON...GOSUB, READ, <a href="/wiki/Comment_(computer_programming)" title="Comment (computer programming)">REM</a>, RESTORE, <a href="/wiki/Return_statement" title="Return statement">RETURN</a>, STOP</span>. In contrast to most dialects, Vilnius did not allow more than one statement per line. </p> <div class="mw-heading mw-heading3"><h3 id="Numeric_variables,_operators_and_functions"><span id="Numeric_variables.2C_operators_and_functions"></span>Numeric variables, operators and functions</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Vilnius_BASIC&action=edit&section=4" title="Edit section: Numeric variables, operators and functions"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>As with most dialects, variable names had to start with a letter and could be followed by more letters or digits. Variable names could be any length, but only the first two characters were stored or matched, meaning that typing <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">PRT001=1</code> followed <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">PR=5</code> would result in a single variable in memory known as PR with the value 5. </p><p>Vilnius BASIC had four basic data types, strings, single and double-precision <a href="/wiki/Floating_point" class="mw-redirect" title="Floating point">floating point</a> numbers, and integers. Unless otherwise denoted, variables were assumed to be double-precision, stored in eight bytes and providing about 17 digits of precision. For comparison, most MS dialects used a <a href="/wiki/Microsoft_Binary_Format" title="Microsoft Binary Format">5-byte format</a> for floating point. If <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">!</code> was suffixed to the variable name, the value was stored in single-precision using four bytes with about 7 digits of precision. <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">%</code> specified an integer, using a single 16-bit word to store values between -32768 and +32767. If a value with more precision was assigned to a variable with less, any excess was simply discarded; <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">A%=1.5</code> will result in A% having the value 1. </p><p>Numeric constants in the <a href="/wiki/Source_code" title="Source code">source code</a> could also be specified as a particular type using the same indicators; <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">50%</code> would store the constant as an integer, <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">0.05!</code> or <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">5E-02</code> stores a single-precision value 0.05, and <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">0.05</code> or <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">5D-02</code> stores the same value in the default double-precision format. Vilnius also had the additional ability to allow numeric constants to be typed in as strings of binary, <a href="/wiki/Octal" title="Octal">octal</a> or <a href="/wiki/Hexadecimal" title="Hexadecimal">hexadecimal</a> characters, by prefixing the string with <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r886049734"><span class="monospaced">&</span> and a single letter indicating the type, B, O, H. For instance, <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">A=&H9A8B</code> would convert the hexadecimal string H9A8B to the equivalent decimal value 39563 and store that in A. </p><p>Operators for numerical values included <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">+, -, *, /, ^</code> adding <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">\</code> for integer division and <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">MOD</code> for the remainder. Thus <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">5\2</code> returns 2, while <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">5 MOD 2</code> returns 1. Numeric functions include the standard <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">ABS, ATN, COS, EXP, INT, LOG, RND, SGN, SIN, SQR, TAN</code>. It also included the <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">FIX</code> operator, which is similar to <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">INT</code> but always truncates toward zero so that <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">FIX(-1.5)</code> returns -1 instead of -2 like INT. </p><p>In addition to <a href="/wiki/PEEK_and_POKE" title="PEEK and POKE">PEEK and POKE</a>, which returned 16-bit values, the system also offered <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">OUT and INP</code>, which were similar but applied a <a href="/wiki/Bit_mask" class="mw-redirect" title="Bit mask">bit mask</a> to the values to allow individual bits to be set or cleared.<sup id="cite_ref-FOOTNOTEManual46_1-0" class="reference"><a href="#cite_note-FOOTNOTEManual46-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">CLS</code> cleared the screen.

One interesting feature of this system was that X,Y coordinates were written in parens. The system remembered the last specified point, and new locations could be indicated with the <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">@</code>, for instance, if the last draw command was at (100,100), one could turn the pixel at (105,105) to color 3 with <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">PSET @(5,5),3</code>. There were five color values, 0 through 3. </p><p>In addition to <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">PSET</code>, one could draw lines from-to using a pair of coordinates separated by a minus sign, similar to the LIST command, for instance <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">LINE (100,100)-(120,120),3</code>. In its simplest form, <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">CIRCLE</code> took an X,Y pair for the center, a radius, and a color, <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">CIRCLE (120,120),30,1</code>. It could also plot arcs from given start and end angles in radians, <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">CIRCLE (120,120),30,1,0,1.5</code>, and could "compress" the vertical axis to produce an ellipse, <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">CIRCLE (100,100),20,1,,,0.4</code>. <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">PAINT (100,100),3,1</code> performed a <a href="/wiki/Flood_fill" title="Flood fill">flood fill</a> starting at (100,100), filling with color 3 and moving outward until it saw color 1. </p><p>Finally, there was the multi-purpose <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">DRAW</code> command. This took a string which encoded a series of drawing steps that could produce a complex shape in a single line of code. The four cardinal directions were indicated with U, D, L and R (up, down, left, right). The 45-degree angles were, moving clockwise, E (up-right), F, G and H (up-left). For instance, <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">DRAW "R20D20L20U20"</code> would produce a square with sides 20 pixels long starting at the last drawn position. In addition to directions, the M command could be used to specify explicit coordinates, like "M100,120", which did not require the parens. C changes the color, B moves without drawing a line, and N resets the coordinates to what they were before the DRAW command. </p><p>There is a single graphics function, <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">POINT(x,y)</code>, which returns the number of the color of that location on the screen. </p> <div class="mw-heading mw-heading2"><h2 id="Example_program">Example program</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Vilnius_BASIC&action=edit&section=7" title="Edit section: Example program"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <pre>1 CLS 2 FOR X%=30% TO 1% STEP -2% 3 ?
