PBL  4DOS  Batch  Command

PBL batch command serves as a simple yet handy interface for the PowerBASIC object module librarian program.  It's a shorthand that "knows" and uses two hardcoded important locations:

%DOS%:\PWRBASIC\PBLIB   PowerBASIC object module librarian program EXE module.
%DOS%:\PBASIC

Directory with MODULE.PBL library of PowerBASIC precompiled subprograms (functions and routines).

PBL batch command simplifies entry into PowerBASIC object module librarian with the help of the KBD program (Marc Perkel, 1990) that places keystroke codes directly into the keyboard buffer, which is used to initiate librarian program.

The most typical usage of the PBL batch command (apart from occasional listing of library modules) is deletion of object module from the library.  This is necessary when new version of the existing module has to be debugged, so that debugging environment would pick the new version, not the old one that's already in the library.

Demo of PBL command operation can be found below the command text.
