/LEFT_MARGIN=n
/LEFT_MARGIN=1 (D)
/LEFT_MARGIN=CONTEXT_DEPENDENT
Specifies the left margin setting that is to be associated with
the language.
If you specify CONTEXT_DEPENDENT as the column number, then LSE
uses the indentation of the current line to determine the left
margin when you use the /WRAP qualifier. When you use the FILL
command, LSE uses the indentation of the first line of each
selected paragraph to determine the left margin.
