This article compares Microsoft BASIC Compiler versions 5.70 and 5.70a
for XENIX 286 to the following compilers:

1. Microsoft QuickBASIC versions 4.00, 4.00b, 4.50 for MS-DOS

2. Microsoft BASIC Compiler versions 6.00 and 6.00b for MS-DOS

Microsoft BASIC Compiler for XENIX 286 provides a library for ISAM
file handling that is not available with the above Microsoft BASIC
compilers for MS-DOS.

Microsoft BASIC Professional Development System (PDS) versions 7.00
and 7.10 provide ISAM file support under MS-DOS (and under MS OS/2 in
BASIC 7.10). BASIC PDS 7.00 and 7.10 offer additional features beyond
those found in 6.00 and 6.00b.

The BASIC compilers for MS-DOS have a graphic capability not found in
the XENIX BASIC compiler.

Compilers under both XENIX and MS-DOS have SUB...END SUB structures
for defining subprograms, which can be called with the CALL statement.

Note: All support and upgrades for Microsoft BASIC Compilers and
Interpreters for XENIX have been assumed by SCO (the Santa Cruz
Operation). For more information on XENIX BASIC and SCO, query on the
following words:

The list below outlines commands that differ between the BASIC
compiler for XENIX versus the BASIC products for MS-DOS.

An asterisk (*) marks words that are reserved, but not functionally
implemented in the compiler.
