Later versions added this feature and improved graphics and other capabilities. It used the CP/M-derived file control blocks for disk access and did not support subdirectories.
CHIPMUNK BASIC RANDOM NUMBER PORTABLE
The initial version of GW-BASIC was the one included with Compaq DOS 1.13 (released with the Compaq Portable in 1983) and was analogous to IBM BASICA 1.10. Some variants of BASIC had extra features to support a particular machine (for example, the AT&T and Tandy versions of DOS included a special GW-BASIC that supported their enhanced sound and graphics capabilities). The former should not be confused with IBM BASICA, which always came as a. Depending on the OEM, BASIC was distributed as either BASICA.EXE or GWBASIC.EXE.
Microsoft did not offer a generic version of MS-DOS until v3.20 in 1986 and before then, all variants of the OS were OEM ones.
CHIPMUNK BASIC RANDOM NUMBER PC
BASICA added a large number of features for the IBM PC such as sound, graphics, and memory commands.
MBASIC programs not using PEEK/POKE statements would run under GW-BASIC. PRINT) do not require a second quote mark at the end unless other arguments followĬonversely, BASIC-80/BASICA/GW-BASIC does not allow the line crunching in 6502 versions (where no spaces are required on a program line). Statements that have quoted text (e.g.The REM statement can be abbreviated as '.Hexadecimal number support (performed by preceding numbers with &H).An advanced editor which included statements for renumbering program lines and deleting them in blocks.DEFINT statement to set all variables beginning with the specified characters as one type, eliminating the need to put type suffixes after them.The ability to save programs in three formats (ordinary tokenized binary, ASCII, or a "protected" token format that cannot be LISTed).PRINT USING statement for formatted display output.Common features of BASIC-80 and BASICA/GW-BASIC include: IBM BASICA and GW-BASIC are direct ports of Microsoft's BASIC-80 (also known as MBASIC) designed for 8080/Z80 machines, but added features specifically for the IBM PC hardware. With the release of MS-DOS 5.0, GW-BASIC's place was eventually taken by QBasic, the interpreter part of the separately available QuickBASIC compiler. Since it was included with most versions of MS-DOS, it was also a low cost way for many would-be programmers to learn the fundamentals of computer programming. The language is suitable for simple games, business programs and the like. Microsoft also sold a BASIC compiler, BASCOM, compatible with GW-BASIC, for programs needing more speed. It was bundled with MS-DOS operating systems on IBM PC compatibles by Microsoft. It is otherwise identical to Microsoft/ IBM BASICA, but is a fully self-contained executable and does not need the ROM BASIC. GW-BASIC is a dialect of the BASIC programming language developed by Microsoft from BASICA, originally for Compaq. IBM Cassette BASIC, IBM Disk BASIC, IBM BASICA
