CA MIM lets you include comments in members of the MIMPARMS and MIMMSGS data sets in two ways:
Place an asterisk character (*) in column 1 to indicate that a line is a comment and not a command or statement.
You can place lines of comments between lines of continued commands or statements.
Place a slash and then an asterisk (/*) before a comment written on a command or statement line to distinguish the comment from the command or statement. The command or statement must precede the /* character string. Otherwise, it is treated as a comment.
