can any one pls guide me what is the difference between ?
1) :
2) &
3)~
4)@
5)@@
They are all different characters? Posting a question with what is XYZ is not helpful, what have you read in the manual on these, where are you using them etc?
At a guess:
1) : - used for stating lists of variables with incremented numeric suffix, like var1, var2 etc.
2) & - And, logic gate
3)~ - could mean anything, I use this as split in report for instance.
4)@ - hold pointer when reading file
5)@@ - hold pointer until next iteration
If the above, then they are all well described in the manual.
@RW9:
3)~ - could mean anything, I use this as split in report for instance.
Actually, it is also an alternative form of the NOT operator, e.g.
408 %put %eval(1~=2);
