SYMPTOMS
DISPLAY STATUS shows only 210 characters of the current setting of the SET PATH TO statement even though the character limit for SET PATH TO is 255 characters.
RESOLUTION
Since this problem is fixed in Visual FoxPro 5.0, the best way to avoid it is by upgrading to Visual FoxPro 5.0.
MORE INFORMATION
The following sample code when run in Visual FoxPro for Windows version 3.0x illustrates the problem:
** *** Sample Program - TESTPATH.PRG
** *** Illustrates DISPLAY STATUS string length limit of SET PATH
CLEAR
