Hi,
Simple question about string functions:
If trim removes trailing blancks and strip = left(trim(var)) , what is the different between trim and strip?, is not the same?
if you remove blancks on the left, then the result is not the same as left(trim..?
isn't it?
Thanks
This is slightly incorrect: strip = left(trim(var))
The correct version would be: strip = trim(left(var))
With that change, there is a difference if you begin with leading blanks.
And the doc SAS(R) 9.2 Language Reference: Dictionary, Fourth Edition has a good list of comparison features.
