PRB: SET FOXPROSWX= in Autoexec.bat File Causes Errors in VFP 6.0 and 7.0 (310423)

The information in this article applies to:

Microsoft Visual FoxPro for Windows 6.0
Microsoft Visual FoxPro for Windows 7.0

This article was previously published under Q310423

SYMPTOMS

You may receive the following errors:

When you start Visual FoxPro (VFP) 6.0 or Visual FoxPro 7.0, you receive the following error:
File '-x.prg' does not exist.
The error can appear with any of the following letters as part of the missing program file name: K, -E, -R, +R, -X, +X, -Y, -M, and ?. -or-
When you create an executable file and try to start it, you receive the following error:
No PARAMETER statement is found.

CAUSE

The Autoexec.bat file contains the following line:

SET FOXPROSWX= -X

FOXPROSWX is an MS-DOS environment variable used in FoxPro 2.6. Valid switches for this environment variable are -C, -T, -K, -E, -R, +R, -X, +X, -Y, -M, and /?.

The error shown in the "Summary" section reflects the first letter assigned to the FOXPROSWX variable. The -C and -T switches do not cause the error because they are valid switches in Visual FoxPro.

RESOLUTION

Remove any reference to the FOXPROSWX environment variable from the Autoexec.bat file.
