yes the 1st one takes 7 bytes for "1"..
second one takes 4 bytes (val "1") and
last one (sgn pi) takes only 2 bytes.
thanks everyone for your help to please my curiousity. -

Handy thread, this. So...
0 = NOT PI
1 = SGN PI
2 = VAL "2"
3 = INT PI
Is there a better one for 2?
What about 4?

I once saw a program where someone recalculated a binary string from INPUT to a decimal number since BIN A$ didn't work.

There are subtle situations where the listing in YS was better though. If you wanted the user to type in a formula then VAL doesn't work to well unless you can persuade them to use e.g. BIN rather than typing B-I-N.New Compo IdeaI've had this idea and would like to know what do you think about it.
