Using the Clipper Program with Windows


To run a program compiled by dBASE, such as Remote Control's Telemagic, with Microsoft Windows, the following line must be entered in the AUTOEXEC.BAT file:
Set Clipper = V12; E000

More Information

The dBASE compiler requires identifiers to write to the screen. The program Clipper is run by dBASE to reserve expanded memory for these identifiers. When a dBASE-compiled program is run by a Windows program information file (PIF), a memory conflict between Windows and Clipper develops.

By entering the above line in the AUTOEXEC.BAT file, Clipper is told to reserve conventional memory rather than expanded memory for the identifiers. The V12; section reserves 12K of conventional memory. The E000 section stops Clipper from seeing any memory above this address. As a result, it does not see expanded memory and uses conventional memory instead.

NOTE: Microsoft does not recommend running program compilers under the Windows environment.
