Onmargin and Offmargin

Activates or deactivates margin marking as discussed in the Including Comments chapter.  The margins are set with $mincol and $maxcol.  The syntax is

$Offmargin

or

$Onmargin

The default is $Offmargin.

Example:

(Margin.gms)

$Ontext

         1         2         3         4         5         6

123456789012345678901234567890123456789012345678901234567890

$Offtext

$Onmargin

$mincol 20 maxcol 45

Now we have        set i plant /US, UK/      This defines I

turned on the      scalar x / 3.145 /        A scalar example.

margin marking.    parameter a, b;           Define some parameters

$Offmargin

Only the black section of the statements are active since they appear between columns 19 and 45, and anything before 19 or after column 45 is treated as a comment.

This results in the LST file segment
