-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Visual FoxPro for Windows, versions 6.0, 7.0 
-------------------------------------------------------------------------------

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.

Steps to Reproduce Behavior
---------------------------

1. Open or create an Autoexec.bat file on a computer that has VFP 6.0 or VFP 7.0

To reproduce the error with the executable, follow these steps:

1. Follow steps 1 and 2 in the previous list.

2. Create a simple executable in either VFP 6.0 or VFP 7.0 and compile it.

3. Try to start the newly created executable and the following error appears:
