If I have "myvar" as a string of variable length, how would I delete the very last character of the string?

I believe this should do it however zmud is not open in front of me to check

myvar=%leftback(@myvar,1)

For more advanced control read up on
%copy, %len

[Edit: Realy it should work now]

Well, it does return the last character, but I couldn't see how it helped me delete that character, since it's not unique and the string has a changing length. This is what I ended up doing...let me know if there's a better way?

#LOOP 1,(%len(@myvar)-1) {#VAR myvar2 {@{myvar2}%copy({@myvar}, %i, 1)}}

According the help file %leftback should work, i also went in and tested and %leftback works and is alot quicker then trying to use a loop

myvar="A String"
myvar=%leftback(@myvar,1)

#SHOW @myvar
A Strin
