languages</a> for computers from <a href="/wiki/Wang_Laboratories" title="Wang Laboratories">Wang Laboratories</a>. The term can be used to refer to the BASIC on any Wang machine, but is mostly associated with the versions on the <a href="/wiki/Wang_2200" title="Wang 2200">Wang 2200</a> <a href="/wiki/Minicomputer" title="Minicomputer">minicomputer</a> series of the early 1970s. When these machines were updated to the VP series in 1976, BASIC-2 was introduced and remained the pattern for future machines in the 2200 series. A planned BASIC-3 was never released. </p><p>Wang offered several models of each version of the 2200 series, differing only in the amount of <a href="/wiki/Microcode" title="Microcode">microcode</a> stored in <a href="/wiki/Read-only_memory" title="Read-only memory">read-only memory</a> (ROM), and thus the number of commands available in BASIC on that machine. For instance, the B model machines differed from the base-model A by doubling the ROM and using that to store a variety of <a href="/wiki/Input/output" title="Input/output">input/output</a> and file management commands. </p><p>Wang BASIC closely followed the original <a href="/wiki/Dartmouth_BASIC" title="Dartmouth BASIC">Dartmouth BASIC</a> in syntax, but was an <a href="/wiki/Interpreter_(computing)" title="Interpreter (computing)">interpreter</a> as opposed to a <a href="/wiki/Compile-and-go" class="mw-redirect" title="Compile-and-go">compile-and-go</a> system. A notable feature was that all math used double-precision <a href="/wiki/Binary-coded_decimal" title="Binary-coded decimal">binary-coded decimal</a> (BCD) format, which was unusual for BASICs of the era.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>a<span class="cite-bracket">]</span></a></sup> It lacked many features common to later dialects like <a href="/wiki/Microsoft_BASIC" title="Microsoft BASIC">Microsoft BASIC</a>, but many of these features were added in BASIC-2. </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=Wang_BASIC&action=edit&section=1" title="Edit section: Description"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The following description is based on the original BASIC found in the 2200A.

For instance, <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">MAT A=B+C</code> would produce a matrix A whose elements were the sums of the corresponding elements in matrix B and C.<sup id="cite_ref-FOOTNOTEWangBASIC1976215_58-0" class="reference"><a href="#cite_note-FOOTNOTEWangBASIC1976215-58"><span class="cite-bracket">[</span>54<span class="cite-bracket">]</span></a></sup> Other matrix commands include <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">INV</code>ert, <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">IDN</code> for the identity matrix and <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">ZER</code> for the zero matrix, and various utilities like <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">COPY</code>, <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">MERGE</code>, <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">MOVE</code> and <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">SORT</code>.<sup id="cite_ref-FOOTNOTEIntro19762_49-1" class="reference"><a href="#cite_note-FOOTNOTEIntro19762-49"><span class="cite-bracket">[</span>45<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="BASIC-2">BASIC-2</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Wang_BASIC&action=edit&section=12" title="Edit section: BASIC-2"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The introduction of the 2200VP's completely new <a href="/wiki/Instruction_set" class="mw-redirect" title="Instruction set">instruction set</a> required an entirely new BASIC to be written from scratch.
