The left arrow on its own is a compiled local variable, and the X and Y are
non-compiled local variables. Hence 3 values are required for your program
to make the value assignments. You need two variables each with left arrow
as the first character in the name.

Subject: [50g] Can anyone answer a question about compiled local variables?

 






I made a program that looks like this: << Right Arrow (0 key) and a left
arrow from the CHAR menu followed by X Y << X Y + >> >>. 

1) No matter what the program is doing it drops 1 number in the stack above
it. 

2) If you only enter two numbers and their is no number above the two level
stack, you get an error.

3) If you try to enter a number into the program before the point where the
variables are initialized, all sorts of weird things happen and it won't let
you.

4) You don't end up with any extra variables at the end of the program
execution but then again I don't think its actually acting as a compiled
local variable with the left arrow added. If you remove it and just use
regular local variables theirs no problems.

5) So, can anybody write a simple program using compiled variables so I
don't have to PURGE all the variables I use all the time?
