ACUCOBOL - This variable holds the full path to the ACUCOBOL-GT installation directory. For example, if when installing ACUCOBOL-GT you accept the default location, the software is installed into C:\ACUCBL40. Therefore, in your configuration file you should set the ACUCOBOL variable accordingly:
ACUCOBOL C:\ACUCBL40
This variable is used to locate COBOL extensions to the runtime. Currently, this variable is used only by client-enabled runtimes (the code that gets the user's password is written in COBOL and contained in the library "acupgms.lib" located in the "lib" subdirectory of the ACUCOBOL home directory).
