The Acu4GL interface for ODBC is an add-on module that comes with a prelinked ACUCOBOL-GT runtime (Version 4.2 or later). The ODBC interface installation includes a .DLL file that is detected at runtime. While in the past, 32-bit users needed to re-link the runtime, this is no longer necessary.
Your diskette from Acucorp contains the pre-linked runtime, which has access to both Vision files and ODBC. The pre-linked runtime executable is named wrunod32.exe for the 32-bit version.
The Acu4GL interface for ODBC can be executed only on a machine that is running Windows 95/98 or later.
