PDL principles and procedures

Comments

Comments are optional statements you may include in the source file to identify sections of the JSL, describe selected PDL commands and their functions, or provide messages for anyone who modifies the JSL later. The system does not perceive these comments as commands and ignores them.

Comments may appear anywhere within the JSL and may consist of multiple records. Comments must be preceded by the character sequence slash asterisk (/*), and terminated by the character sequence asterisk slash (*/). For example:

/*System commands are coded here.*/

Nested comments A comment may also be nested within another comment. There is no practical limit to the level of nesting possible, as long as each nested comment is preceded by a slash and an asterisk (/*) and succeeded by an asterisk and a slash (*/). An acceptable nested comment format is as follows:

/* comment /*

nested comment */ */

Note that the illustration above ends with two */ markers: the first for the nested comment and the second for the main comment.

Ending a JSL

What may follow the END; command

A JSL terminates with the END command. When you are finished constructing your JSL, you must let the system know you are finished by entering the END; command, as shown below. This also applies to CMEs, PDEs, TSTs, and STOCKSETs you are coding.

END;

After you end a JSL, you may still code certain items following the END; command.

Subsequent JSLs: Following the END; command for one JSL, you may code additional JSLs. If one JSL is to follow another, the next command after the END; command should be another “JDL” command.
