MBASIC was one of the two versions of BASIC bundled with the <a href="/wiki/Osborne_1" title="Osborne 1">Osborne 1</a> computer. The name "MBASIC" is derived from the disk file name MBASIC.COM of the BASIC interpreter. MBASIC, like its predecessor family of 8-bit interpreters <a href="/wiki/Microsoft_BASIC" title="Microsoft BASIC">Microsoft BASIC</a>, were heavily inspired by <a href="/wiki/Digital_Equipment_Corporation" title="Digital Equipment Corporation">Digital Equipment Corporation</a> <a href="/wiki/PDP-10" title="PDP-10">PDP-10</a>'s <a href="/wiki/BASIC-PLUS" title="BASIC-PLUS">BASIC-PLUS</a>. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Environment">Environment</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=MBASIC&action=edit&section=1" title="Edit section: Environment"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:MBasic_5.21.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/1/17/MBasic_5.21.jpg/220px-MBasic_5.21.jpg" decoding="async" width="220" height="164" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/1/17/MBasic_5.21.jpg/330px-MBasic_5.21.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/1/17/MBasic_5.21.jpg/440px-MBasic_5.21.jpg 2x" data-file-width="2692" data-file-height="2008" /></a><figcaption>MBasic 5.21 running on a Z80 CP/M system displayed on a monochrome monitor typical for that time</figcaption></figure> <p>MBASIC version 5 required a CP/M system with at least 28 KB of <a href="/wiki/Random-access_memory" title="Random-access memory">random-access memory</a> (RAM) and at least one diskette drive. </p><p>Unlike versions of <a href="/wiki/Microsoft_BASIC-80" class="mw-redirect" title="Microsoft BASIC-80">Microsoft BASIC-80</a> that were customized by <a href="/wiki/Home_computer" title="Home computer">home computer</a> manufacturers to use the particular hardware features of the computer, MBASIC relied only on the CP/M operating system calls for all input and output. Only the CP/M console (screen and keyboard), <a href="/wiki/Line_printer" title="Line printer">line printer</a>, and disk devices were available. </p><p>MBASIC in the uncustomized form had no functions for <a href="/wiki/Computer_graphics" title="Computer graphics">graphics</a>, color, joysticks, mice, <a href="/wiki/Serial_port" title="Serial port">serial communications</a>, <a href="/wiki/Ethernet" title="Ethernet">networking</a>, sound, or even a <a href="/wiki/Real-time_clock" title="Real-time clock">real-time clock</a> function. MBASIC did not fully support the features of the host CP/M operating system, for example, it did not support CP/M's user areas for organizing files on a diskette. Since CP/M systems were typically single-user and stand alone, there was no provision for file or record locking, or any form of <a href="/wiki/Computer_multitasking" title="Computer multitasking">multitasking</a>. Apart from these limitations, MBASIC was considered at the time to be a powerful and useful implementation of BASIC. </p> <div class="mw-heading mw-heading2"><h2 id="Features">Features</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=MBASIC&action=edit&section=2" title="Edit section: Features"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="mw-heading mw-heading3"><h3 id="Language_system">Language system</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=MBASIC&action=edit&section=3" title="Edit section: Language system"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>MBASIC is an <a href="/wiki/BASIC_interpreter" title="BASIC interpreter">interpreter</a>. Program source text was stored in memory in tokenized form, with BASIC keywords replaced by one-byte tokens which saved memory space and speeded execution. Any line prefixed with a line number was stored as program text; BASIC statements not prefixed with a line number were executed immediately as commands. Programs could be listed on the screen for editing, or saved to disk in either a <a href="/wiki/Data_compression" title="Data compression">compressed</a> binary format or as plain <a href="/wiki/ASCII" title="ASCII">ASCII</a> text. Every source line was identified with a number, which could be used as the target of a <a href="/wiki/GOTO" class="mw-redirect" title="GOTO">GOTO</a> or <a href="/wiki/GOSUB" class="mw-redirect" title="GOSUB">GOSUB</a> transfer. Only line editing commands were provided.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> It was often beneficial to save a program as plain text and edit it with a full featured editor. </p><p>Program text, <a href="/wiki/Variable_(computer_science)" title="Variable (computer science)">variables</a>, <a href="/wiki/Disk_buffer" title="Disk buffer">disk buffers</a> and the CP/M operating system itself all had to share the 64 kilobyte address space of the <a href="/wiki/Intel_8080" title="Intel 8080">8080</a> processor. Typically when first starting MBASIC there would be less than 32 kB memory available for programs and data, even on a machine equipped with a full 64 kilobytes of RAM. Comment lines, prefixed with the <code> REM </code> keyword or an apostrophe, could be placed in the program text but took up valuable memory space, which discouraged BASIC users from fully documenting their code. To allow larger and more complex programs to be run, later versions of MBASIC supported functions that allowed portions of program text to be read in and executed under program control (the "<a href="/wiki/Chain_loading" title="Chain loading"><code> CHAIN </code></a>" and <code> MERGE </code> statements). No support for "shell" command execution was provided, though this functionality could be duplicated by a determined programmer. </p><p>A particular advantage of MBASIC was the full-text error messages provided for syntax and run-time errors. MBASIC also had a "trace" function that displayed line numbers as they were executed. While this occupied the same screen space as normal program output, it was useful for detecting conditions such as <a href="/wiki/Endless_loop" class="mw-redirect" title="Endless loop">endless loops</a>. </p> <div class="mw-heading mw-heading3"><h3 id="Files_and_input/output"><span id="Files_and_input.2Foutput"></span>Files and input/output</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=MBASIC&action=edit&section=4" title="Edit section: Files and input/output"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Data could be read and stored to disk as either sequential files (delimited by the CP/M convention of <a href="/wiki/Carriage_return" title="Carriage return">CR</a>/<a href="/wiki/Line_feed" class="mw-redirect" title="Line feed">LF</a> at the end of each line) or else as fixed-record-length random access files, which, given a sufficiently determined programmer, could be used to perform database-type record manipulation. The <a href="/wiki/Microsoft_Binary_Format" title="Microsoft Binary Format">Microsoft Binary Format</a> for <a href="/wiki/Floating_point" class="mw-redirect" title="Floating point">floating point</a> numbers was proprietary to the implementation, which meant that data could only be interchanged with other programs using ASCII text representation or else with extensive programming to convert the binary format. </p> <div class="mw-heading mw-heading3"><h3 id="Variables_and_data_types">Variables and data types</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=MBASIC&action=edit&section=5" title="Edit section: Variables and data types"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>MBASIC supported the following data types: </p> <ul><li>8-bit character data, in strings of length 0 to 255 characters;</li> <li>16-bit <a href="/wiki/Integer" title="Integer">integers</a>;</li> <li>32-bit <a href="/wiki/Floating_point" class="mw-redirect" title="Floating point">floating point</a> (single precision), equivalent to six decimal digits, with a two-digit exponent;</li> <li>64-bit floating point (double precision), equivalent to sixteen decimal digits, with a two-digit exponent.</li></ul> <p>String operators included substring selection, concatenation, assignment, and testing for equality. </p><p>Arrays of the above types were allowed with up to 7 dimensions, but no functions or operators worked on arrays; for example, there was no assignment of arrays. Unlike some other BASIC implementations of the time, MBASIC did not provide support for <a href="/wiki/Matrix_(mathematics)" title="Matrix (mathematics)">matrix</a> operations, <a href="/wiki/Complex_number" title="Complex number">complex numbers</a>, or a <a href="/wiki/Binary-coded_decimal" title="Binary-coded decimal">decimal (BCD)</a> data type for financial calculations. All floating point operations were carried out in software since typical CP/M systems did not have <a href="/wiki/Floating-point_unit" title="Floating-point unit">floating point hardware</a>.

Since these systems typically had no <a href="/wiki/Memory_protection" title="Memory protection">memory protection</a>, this allowed a programmer to access portions of the operating system, or functions that would not otherwise be available. This also provided opportunities for user programs to hang the system (by accident, usually). For example, a CP/M programmer might use a <code> POKE </code> function to allow BASIC to switch the console device to the serial port, if the system <a href="/wiki/BIOS" title="BIOS">BIOS</a> supported this. For machines with real-time clocks, a set of <code>PEEK</code> instructions might have been used to access the time. </p><p>For more complex operations, MBASIC allowed user-defined functions that could be called from a BASIC program.

MBASIC also provided hardware <code>INP</code> and <code>OUT</code> instructions that read and wrote directly to the 8080 hardware input/output ports.
