Variable X has a length of 20 so when the concatenation takes place, the trailing blanks remain on the value. When the TRIM function is used, those trailing blanks are trimmed so that the X and Y variables are put together with no space between them.

Since character variables are padded with blanks up to the length of the variable, the TRIM function is needed to trim those blanks before concatenating to another variable.
