4.00 MS-DOS
Summary: You can use PWB’s “deflang” switch to change the default filename extension to .CBL for PWB list boxes. This information applies to the Programmer’s WorkBench (PWB) version 1.10 provided with Microsoft COBOL Professional Development System (PDS) version 4.00 for MS-DOS and MS OS/2.
More Information: By default, deflang is not set. By default, an Open from PWB’s File menu gives a list of . files from the specified directory. (All of the files are listed in alphabetic order.) If you want to have only the COBOL source listed, you can set the deflang switch in the [PWB] tagged section of the TOOLS.INI file. For example: deflang:CBL This changes the default filename extension in the PWB’s dialog boxes (such as Open in the File menu) from . to *.CBL, so that only files with the .CBL extension show up by default. Other languages can be specified as well, as shown below:
Switch Setting | Extension |
---|---|
no value | .* |
C | .c |
Asm | .ASM |
BASIC | .BAS |
FORTRAN | .FOR |
Pascal | .PAS |
COBOL | .CBL |
LISP | .LSP |
Note that PWB’s online documentation incorrectly specifies “Assembler” as the switch to use for .ASM files. “Asm” is the correct switch to use to make Assembler the default language.
