Thanx all for your attention.
The page showed some examples when I recalled, it looks like(not sure)
following:
------------------------------------
If condition then
xxxxxxxx
End if
or----------------------------------
For condition
xxxxxxxx
Next
------------------------------------
It seemed to be different from "dos programing" of older version.
I might apply it to more complex variations.
It's what my requests originally.
Usually,I used vbscripts instead of "dos batch" if more conditions needed to
be considered.
Your responses did me a great favor and corrected many wrong concepts of
mine.
I'll try to find out the page and forward it on here if possible.
Thanx everyone responded.
