The Trim Whitespace (STRTRIM) instruction will remove all whitespace characters from the beginning and / or end of a String. Whitespace characters between characters in the string are not removed. Whitespace characters typically represent horizontal or vertical space, the ones the Trim Whitespace instruction will remove are Space <SP>, Horizontal Tab <TAB>, Carriage Return <CR>, Line Feed <LF>, Form Feed <FF>, Vertical Tab <VT>.
