length of lstring only if the specified length is less than the trimmed length of the string.

length
-
is the length in which the character string is to be left-justified. The default is the maximum length of lstring.
Type:
Numeric
Any leading blanks in the string are removed so that the first character in the string is nonblank. The default length of the
returned value is the trimmed length of the left-aligned string. Use length to specify a different maximum length for the returned string.
In
order for LEFT to work properly when lstring is a window variable, set the justification field (JUST) in the field attribute window for
lstring to NONE.
To right-justify a character string, use RIGHT. To center a character string, use
CENTER.
