PRB: SHOW GET <Var> ENABLE/DISABLE on Zero-Length Memvar

ID: Q116036

The information in this article applies to:

Microsoft FoxPro for MS-DOS, versions 2.0, 2.5, 2.5a, 2.5b
Microsoft FoxPro for Windows, versions 2.5, 2.5a, 2.5b
Microsoft FoxPro for Macintosh, versions 2.5b, 2.5c

SYMPTOMS

If you set a memory variable equal to "" (an empty string of zero length) in order to clear out the variable GET field, and you then disable the field with the SHOW GET <var> DISABLE command, FoxPro will clear the memory variable and disable the field; however, if you later want to enable the field, the field won't be accessible after you issue the SHOW GET <var> ENABLE command because the memory variable has no value to display.

RESOLUTION

Instead of assigning the memory variable to "", assign the memory variable to a string of spaces the length of the memory variable. For example:

   m.company="                    "
   or m.company=SPACE(25)
