>My company has purchased an VFP application (along with source code).
>The application consists on one main executable and an .app for each module (AR.app, AP.app, etc). My problems is that the application uses 12 MB of memory upon loading (with no forms active and no cursors populated). The main execuatable simply executes each app with a do command and the app's simply execute a menu (.mpr) program.

SYS(3050) can be used to control how much memory will be used by VFP for buffer space; there's a base minimum memory use in the 1-2MB range, and then SYS(3050,1,Memory in bytes) is used to set memory usage when a VFP app is in the foreground, and SYS(3050,2,Memory in bytes) to set the value when VFP is in the background. The docs say that VFP will set the value to 256K if no value is specified; my experience has been that setting it below about 2MB really hurts performance badly. Setting it to 2MB, should let each VFP instance tie up around 4MB of RAM while executing.

If you work with large tables, or a large number of tables, within your application, you are likely to degrade performance adjusting this value.
