Well, I figured it was one of those, but I wanted to know specifically from the OP. The reason is that the OP is being told not to use ">" and "<", but instead use -gt -lt instead.
If you have a "-gt" in your script and run ksh -n scriptname, it will tell you this:
warning: line 3: -gt within [[...]] obsolete, use ((...))
I just didn't want the poster to think they were necessarily doing that part incorrectly...

LivinFree, the behavior you describe should only happen if you are using ksh93 (not ksh88) and you have used the -n option and you are using [[. Even with ksh93 and the -n option set, it should not complain about -gt in a single bracket test. And the single bracket test is the only one being mentioned in this thread.
