Function LTrim() Foundation

Removes blank spaces at the beginning of a character string.

Syntax
LTrim( <cString> ) --> cTrimString
Parameters
<cString>
<cString> is a character string which is copied with blank spaces at the beginning removed.
Return

LTrim() returns a copy of <cString> with all leading blank spaces (Chr(32) only) removed. When <cString> is an empty character string or consists only of blank spaces, the return value is a null string ("").

Description

The character function LTrim() is used for formatting character strings whose first characters consist of blank spaces (Chr(32)). LTrim() is often used when a number is converted to a character string with Str() and this character string is needs further processing without leading blank spaces.

LTrim() resembles the function RTrim() and Trim() which remove the blank spaces at the end of a character string. Another function that removes blank spaces is Alltrim(), which removes blank spaces at the beginning and the end of a character string. The functions LTrim(), RTrim() and Alltrim() are the inverse of the functions PadL(), PadR() and PadC() which insert blank spaces at the beginning, the end, and at the beginning and end of a character string, respectively.
