Summary:
The Programmer's WorkBench (PWB) versions 1.0 and 1.1 can be
configured for specific operating systems by creating special "tagged"
sections in the TOOLS.INI file. If you want to create tagged sections
for DOS versions 4.0, 4.01, or 5.0, then there are specific
requirements for the tags themselves in order for PWB to correctly
recognize them.
More Information:
Creating operating system specific PWB tags in TOOLS.INI is described
on page 160 of the "Microsoft C Advanced Programming Techniques"
manual that ships with Microsoft C versions 6.0, 6.0a, and 6.0ax, and
on page 393 of the "Microsoft Macro Assembler Programmer's Guide" that
ships with the Microsoft Macro Assembler (MASM) version 6.0.
The tag for an operating system specific section of TOOLS.INI contains
one or more operating system versions. PWB will not read the section
unless the specified operating system is in use. For example, the
section of TOOLS.INI under the tag [PWB-3.31] will only be recognized
if you are using MS-DOS version 3.31.
When specifying operating system version numbers in TOOLS.INI tags for
MS-DOS version 4.0, 4.01, or 5.0, the following requirements must be
observed:
1. For MS-DOS 4.0 or 5.0, you will need to use the tags [PWB-4.0] or
[PWB-5.0], respectively. Although the version number is carried out to
the hundredths place for MS-DOS 3.31 and earlier, it is only carried
out to the tenths place for versions 4.0 and 5.0. If you place an
extra zero in the tag (for example, [PWB-4.00]), that section of the
TOOLS.INI file will not be recognized.
2. If you are using MS-DOS 4.01, you must use the tag [PWB-4.0]. PWB
does not distinguish between MS-DOS versions 4.0 and 4.01 because
MS-DOS 4.01 returns 4.0 as the operating system version number.
