PRB: DISPLAY STATUS Shows Only 210 Characters of SET PATH TO

• Pro Edition of Microsoft Visual FoxPro for Windows, versions 3.0, 3.0b

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

** *** S2 length = 210 represents maximum length shown as result of DISPLAY STATUS

s2="c:\vfp30b;c:\vfp30b\api;c:\vfp30b\api\samples;c:\vfp30b\distrib.src;c:\ vfp30b\distrib.src\setup;c:\vfp30b\distrib.src\setup\setup16;c:\vfp30b\dist rib.src\setup\setup32;c:\vfp30b\distrib.src\system;c:\vfp30b\dis"

** *** S3 length = 255 which is maximum string length before giving ** ***

'Syntax Error'

** *** cannot set S4 since it gives syntax error. ** *** s4="c:\vfp30b;c:\vfp30b\api;c:\vfp30b\api\samples;c:\vfp30b\distrib.src;c:\ vfp30b\distrib.src\setup;c:\vfp30b\distrib.src\setup\setup16;c:\vfp30b\dist rib.src\setup\setup32;c:\vfp30b\distrib.src\system;c:\vfp30b\distrib.src\sy stem\system16;c:\vfp30b\distrib.src"

   ?LEN(s1)
   SET PATH TO &s1
   ?"RETURN VALUE OF ?SET('PATH') is:"
   ?SET("path")
   DISP STAT

   CLEAR
   ?" S2 length = "
   ??LEN(s2)
   ??"  which is the maximum display length of DISPLAY STATUS"
   SET PATH TO &s2
   ?"RETURN VALUE OF ?SET('PATH') is:"
   ?SET("path")
   DISP STAT

   CLEAR
   ?" S3 length = "

   ??"  which is the maximum length before giving 'Syntax Error'"
   SET PATH TO &s3
   ?"RETURN VALUE OF ?SET('PATH') is:"
   ?SET("path")
   DISP STAT

   CLEAR
   ?" S4 cannot be set since it is one greater than s3 (which is "
   ?? ALLTRIM(STR(LEN(s3)))
   ??") and would give 'Syntax Error'"
