SYMPTOMS

The following error message occurs when you attempt to start an MS-DOS session from FoxPro for Windows using the RUN or "!" (without the quotation marks) commands:

Insufficient memory for application's required space. Decrease PIF KB Required, or quit one or more applications, or free up disk space, to increase available memory. Then try again.

CAUSE

There is not enough free virtual or physical memory to start the MS-DOS-based program.

RESOLUTION

Use one of the following methods to increase the amount of free memory:

Method 1

Increase the size of the Windows swap file and, if you are using Windows 3.1, enable 32-bit disk access if possible. Windows needs less free physical RAM to run an MS-DOS session when 32-bit disk access is turned on. To modify the swap file and turn on 32-bit disk access:

  1. From the Main group in Program Manager, run the Control Panel then choose the 386 Enhanced icon.
  2. Choose the Virtual Memory button.
  3. Choose the Change button.
  4. Select the type of virtual memory you want to use (Temporary or Permanent) from the Type list box, then enter a larger size in the New Size box. The new swap file does not take effect until Windows is restarted. If you select a permanent swap file and have a compatible hard drive controller, the 32-Bit Disk Access check box is displayed. If the check box is empty, select it to enable 32-bit disk access.

Method 2

Quit any other MS-DOS-based programs that are currently running.

Method 3

Use the PIF Editor, located in the Main group in Windows 3.1, to open the FOXRUN.PIF file, which is located in the FoxPro development directory (usually FOXPROW). Decrease the KB Required value for any or all of the following areas: Memory Requirements (conventional memory), EMS Memory, or XMS Memory.

MORE INFORMATION
