Steps to Reproduce Problem
--------------------------

Create and run a program containing this code:

     * Start of program
     *
     * This program assumes the existence of the file 'autoexec.bat' in the
     * c:\ directory.
     * Example - does not find file

     SET DEFAULT TO c:\temp   && This directory must exist
     SET PATH TO c:\ 
     nhand=FOPEN('autoexec.bat')   && Returns -1  -  FOPEN failed
     ?STR(nhand)+ " In SET PATH"

     * The following command returns 2 for "File not found"
     ?STR(FERROR()) + " FERROR Code"
     =FCLOSE(nhand)

     * Workaround 1 - finds file

     SET DEFAULT TO c:\ 
     nhand2=FOPEN('autoexec.bat')  && FOPEN succeeds in default directory
     ?STR(nhand2) + " In SET DEFAULT"
     =FCLOSE(nhand2)

     * Workaround 2 - finds file

     SET DEFAULT TO c:\temp   && This directory must exist
     nhand3=FOPEN('c:\autoexec.bat')   && FOPEN succeeds with path passed
     ?STR(nhand3) + " Path explicitly passed to FOPEN"
     =FCLOSE(nhand3)

        * End of program
