'    DOLIB is a program to update the private libraries used with      *
' Microsoft BASIC compiler (BC) version 7.  It adds (or replaces)      *
' named modules to the private searchable libraries, PB.LIB and        *
' PBF.LIB, by constructing and then running a batch file.  The batch   *
' file also runs the compiled BASIC program PBBI.EXE to update the     *
' declaration header file, PB.BI.                                      *
'    The command-line call is "DOLIB [<path>]<modname>"                *
'           where <modname> is the name of the module to be added.     *
'                 <path> is required if the source-code file for       *
'                        <modname> is not in a directory in the PATH   *
'                        environment string.                           *
'    If the source file for <modname> is <modname>.ASM, DOLIB will be  *
' assembled before adding it to both libraries.  If the source file is *
' <modname>.BAS, the file will be compiled twice: in default mode for  *
' PB.LIB, and for "far strings" for PBF.LIB.  If the BASIC source file *
' contains local error trapping, the compilation will be made with the *
' "/E" switch.                                                         *
'    DOLIB updates copies of the libraries and header file in the      *
' default directory.  If any of these files is not in the default      *
' directory, DOLIB will copy it from the directory named in the LIB or *
' INCLUDE environment string.  If <modname> already exists in either   *
' library copy, it will be replaced by the new version.  An existing   *
' SUB or FUNCTION declaration statement in the PB.BI file for the same *
' procedure name will be replaced.                                     *
