@ ... GET List Behavior Difference with Disabled Options

ID: Q103605

The information in this article applies to:

  • Microsoft FoxPro for Windows, versions 2.5 and 2.5a
  • Microsoft FoxPro for MS-DOS, versions 2.0, 2.5, and 2.5a

SUMMARY

Disabled options in a GET list can be selected in FoxPro for Windows unlike in FoxPro for MS-DOS. When selected, the variable will yield the null string or 0 (this depends on how the variable was declared).

MORE INFORMATION

To see the difference in behavior, do the following procedure in FoxPro for Windows and in FoxPro for MS-DOS:

1. Run the code included below.

2. Press the DOWN ARROW until you reach the test5 option, which is

   disabled, and press the ESC key.

FoxPro for MS-DOS will not allow the test5 option to be highlighted, but FoxPro for Windows will; FoxPro for Windows will also yield 0 when the option is highlighted.
