Continuing JCL statements that contain symbols z/OS MVS JCL Reference SA23-1385-00 |
|
The system evaluates continuations of JCL statements that contain
symbols as follows:
For example, consider the following JCL:
The JCL records that define step S1 form a valid continuation; the JCL symbol VAL1 introduces a comma, and the continuation is correctly coded. Steps S2 and S3 are not valid. In step S2, the first record does not end in a comma after substitution of VAL2. In step S3, the record containing NULLSYM evaluates to a null record after symbolic substitution. It may be that the number and length of symbols form a parameter that does not fit within the limits imposed by an 80-character record. (In reality the limit is 68 characters, because columns 1, 2, and 3 must contain respectively a slash, slash, and blank, and column 72 must be blank.) Two techniques for handling this situation are: (1) defining shorter symbols to substitute for the longer ones, or (2) dividing the series of symbols so as to form two parameters, which would allow you to place a comma after the first and move the second to a continuation record. |
