characters removed, depending on the %Where parameter.

trailing spaces from.

from. Valid constants are BOTH, LEFT, and RIGHT. If not specified,

the default %Where is BOTH.

N/A

Example:

//create a string of spaces

$Spaces := REPSTR( “ ”, 10)

//create a string containing leading and trailing spaces

$String := $Spaces + “string” + $Spaces

%Len := LEN( $String) // 26

%Len := LEN(TRIMSTR( $String)) // 6

$Trimmed := TRIMSTR( $String, LEFT))

%Len := LEN( $Trimmed) // 16
