TRIM [ /Blanks ] [ /Characters=abcde ] /Leading|Trailing [ /Variables ] /- string(s)
TRIM command removes characters from the beginning and/or from the end of one or more strings.
For each supplied string, the STx
TRIM command will remove all leading (option "
/Leading") and/or trailing ("
/Trailing") occurrences of any white space character (option "
/Blanks") and/or of any character supplied as an argument to the "
/Characters" option (both options may be combined).
The command returns the trimmed strings or, if more than one string is supplied, a blank-separated list of trimmed strings.
If option "
/Variables" is supplied, the arguments are considered to be the names of STx variables. In this case, the trimmed content of the respective variables is returned. The variables themselves are not altered.
