STRING.trimWhiteSpace

Removes leading and trailing whitespace characters.

Syntax

trimWhiteSpace( )
       RETURNS STRING

Usage

The trimWhiteSpace() method removes the leading and trailing whitespace characters of the current STRING variable and returns a new string.

Note: The method considers as whitespace characters all characters less than or equal to blank space (ASCII(32)). This includes tab (\t), newline (\n), carriage-return (\r) and form-feed (\f).

If the original STRING variable is NULL, the result will be NULL.

Example

MAIN
  DEFINE s STRING
  LET s = "\n\t Some text \n\t"
  DISPLAY "["||s.trimWhiteSpace()||"]"
END MAIN

Output:

[Some text]
