can simply pass this:

I agree about simpler to read.

But I wonder about saving CPU cycles and unnecessary %trims. If you don't use %trim to get the length, then you just move the processing of the trailing blanks to the CL command processor. Probably makes no difference, although it somehow feels like it's more complex for the command processor to handle trailing blanks. I have no idea how the command parsing works, maybe it even trims before it starts. But if it just chugs through the entire input string, it might do a bit more work for each character than %trim does. For instance, when it finds a blank, it may have to also check whether it's processing a literal before it decides whether to ignore the blank or not.
