1. CONFIGURING dBASE'S VIRTUAL MEMORY MANAGER (VMM) --------------------------------------------------- When you run BDC or a dBASE executable file on a system with less than 4.5MB extended memory, dBASE's VMM runs automatically and manages your system's memory and disk space for the best performance. You can customize VMM's settings by modifying its configuration file, DBASE.VMC, located in the Compiler home directory. If you want to customize the environment that your executable file is running in, you must rename DBASE.VMC to the name of your executable file. For example, if the name of your executable file is TEST.EXE, rename DBASE.VMC to TEST.VMC. Then, when you run TEST.EXE, VMM will use the memory settings you specified in TEST.VMC. If you want to limit the amount of memory that dBASE Compiler for DOS or your executable file uses without modifying the .VMC file, you can use the DOS environmental variable, DOS16M. For example, SET DOS16M=:4M limits the Compiler or your executable file to 4MB of memory. 2. RUNNING AN EXECUTABLE FILE IN MULTIPLE SESSIONS -------------------------------------------------- If you run your executable (.EXE) file in multiple sessions under Windows, you must set the file as read-only to avoid share violations. 3. SELECTING DBASE.RES ACCORDING TO DOS CODE PAGE ------------------------------------------------- If you run executable with DOS codepage 437, copy dbase.437 to dbase.res. If your codepage is 850, copy dbase.850 to dbase.res.
