VFP 6.0 does a weird inconsistent trucation of paths in Win 98 but not NT 4.0:

The Following code illustrates it

CLEAR
?"On Win 98 the following path command takes."
?"The entire path is accepted --including "
?"The redundant 'C:\MMORTALS\COMMON30\INCLUDE'"
?"which appears a second time as specified."
SET PATH TO DATA, LIBS, PROGS, INCLUDE,  GRAPHICS, HELP, ;
MENUS, METADATA, REPORTS, ;
\MMORTALS\COMMON30\LIBS, ;
\MMORTALS\COMMON30\PROGS, ;
\MMORTALS\COMMON30\UTILS, ;
\MMORTALS\COMMON30\GRAPHICS,;
\MMORTALS\COMMON30\INCLUDE,;
I:\DEVELOPMENT\DATA\MAIN, ;
\MMORTALS\COMMON30\INCLUDE

*C:\MMORTALS\COMMON30\UTILS
?
?
?SET("PATH")
?
?
?"But drop the redundant 2nd dir and the path is truncated."
?"all the way back to '\MMORTALS\COMMON30\GRAPHICS'."
?"It is (of coure) the string length not the contents."
?"Any expression of the same length can be substituted for"
?"the final directory. Changing the lengths of other"
?"directories sometimes cause truncation, sometime not."
?
?
SET PATH TO DATA, LIBS, PROGS, INCLUDE,  GRAPHICS,;
MENUS, METADATA, REPORTS, ;
\MMORTALS\COMMON30\LIBS, ;
\MMORTALS\COMMON30\PROGS, ;
\MMORTALS\COMMON30\UTILS, ;
\MMORTALS\COMMON30\GRAPHICS,;
\MMORTALS\COMMON30\INCLUDE,;
I:\DEVELOPMENT\DATA\MAIN
?SET("PATH")

Note that the above code will accept all paths given in windows NT 4, but not in 98 or Windows 2000
