Modify static subsystem catalog
Function
This statement allows an existing static subsystem catalog to be modified. New SSD objects containing the definitions of the subsystems can then be inserted in this file.
The definition of a modified catalog is terminated by means of the statements CHECK-CATALOG statement and SAVE-CATALOG statement .
START-CATALOG-MODIFICATION will be rejected if the name specified for the file does not exist, or was not created beforehand by means of a START-CATALOG-CREATION statement.
If there are two consecutive START-CATALOG-MODIFICATION statements or if START-CATALOG-MODIFICATION is specified after the statement START-CATALOG-CREATION without a concluding SAVE-CATALOG statement, the following message will be displayed in interactive jobs:
SCM0011 DO YOU REALLY WANT TO OVERWRITE MEMORY CATALOG '(&00)'? REPLY (Y/N)
If the reply is Y, the reserved memory space will be released, and the changes just made to attributes of the catalog will be abandoned.
If the reply is N, the second START-CATALOG-MODIFICATION statement is considered invalid, and the first statement can be concluded with SAVE-CATALOG.
In the case of batch jobs, the response Y is given implicitly.
