When you have coded the DFHSIT macro, you must assemble and link-edit the table into an APF-authorized library, such as CICSTS31.CICS.SDFHAUTH, and include this library in the STEPLIB concatenation of the startup job stream. For information about assembling and link-editing CICS® control tables, and an explanation of the syntax notation used to describe CICS macros, see the CICS Resource Definition Guide.
If you code a system initialization parameter in your SIT source, and the parameter’s keyword is not defined in the CICS-supplied version of the DFHSIT macro, you get an IEV017 warning message from the assembly, as follows:
IEV017 ** WARNING ** UNDEFINED KEYWORD PARAM. DEFAULT TO
POSITIONAL, INCLUDING KW -- OPENC/aaaaaaa
where: aaaaaaa is the unidentified keyword.
However, be aware that because of work space limitations there is a limit to the number of undefined keyword errors that the assembler can generate. This means that if your SIT contains more undefined keywords than the assembler can generate messages for, some are not flagged until a second (or even later) assembly, and as you correct flagged errors, other errors (previously unflagged) may appear during reassembly.
