Description
The Trim command removes whitespace from both ends of the aString parameter and returns a new string, without modifying the original one. Whitespace includes spaces, tabs, LF, CR, etc.
To return a new string with whitespace trimmed from just one end, use Trim start or Trim end.
In the aString parameter, you can pass any text expression. It will be left untouched by the command.
The command returns the trimmed version of the aString string. If there is no whitespace at any end of aString, the returned string is identical as the one passed in parameter.
note
This command is based upon the TrimString Ecmascript specification.
Example
var $input; $output : Text
$input:=" Hello World! "
$output:=Trim($input) //"Hello World!"
