Comment

This changes the character normally used in column 1 to start a comment from * to the single character specified as discussed in the Comment chapter.  This command is invoked using the syntax

$comment character

where character is a one character specification of the new item to use.  Note this item should be carefully chosen to not conflict with other usages of the newly chosen character.  An example follows (commentdol.gms):

*normal comment

$comment !

!comment with new character

The case of character does not matter when being used.
