What system do you use? Where are you try your loops - on the command line? Or in a script and what is the first line of your script in this case?

He or she probably using older version of KSH.
In KSH93 it should work fine.

Try this to accomplish the same thing in current ksh :
Code:
a=1
while [ $a -le 5 ]; do
echo $i
((a+=1))
done

"Still getting the same error" without answering any of yazus questions doesn't tell us anything. It's like telling the doctor "It's still hurting" when being asked where it hurts.

sorry for that Smilie, wrongly copied.

AIX-P550, i'm trying to execute the for loop in script.

#!/usr/bin/ksh is the first line

Thanks

That's my fault. I corrected my post. I was fast, but girish_satyam was faster. Smilie
Sorry but I know almost nothing about AIX.
