Comment and Continuation Rules

You can use comments and line continuations within the SYSIN control statements.

Comment cards are characterized by an asterisk in column one and can be inserted anywhere within the control statements.
Comments can be placed after any command or keyword if they are followed by at least one space.
Command continuation is designated by a comma followed by at least one space.
Keywords can be continued on the next card by using a comma and a space following any parameter.
