This option specifies the margin indicator used in the source listing produced.
>>-MARGINI--(--'char'--)---------------------------------------><
ABBREVIATIONS: MI('char')
The character, char, is inserted in the positions immediately to the left and right of both side margins, making any source code outside of the margins easily detected.
DEFAULT: MARGINI(' ')
Using the default specifies that left and right source margins are shown in the listing by blank columns.
For a sample listing, see Using the compiler listing.
