Never mind, you guys are too slow. I wrote my own. :-)

FUNCTION LeftJustify, theString, theWidth

IF N_Elements(theString) EQ 0 THEN RETURN, ""
IF N_Elements(theWidth) EQ 0 THEN theWidth = 50

justifiedString = String(BytArr(theWidth) + 32B)
StrPut, justifiedString, theString
RETURN, justifiedString

END

Cheers,

David
