Parameters

BRANCH=: YES specifies that code generated by expansion of this macro will include a branch around the identification statements. NO specifies that no branch is to be included.
LEVEL=: Specifies the release, the feature, or the SU of the module.
ID=: Specifies the name of the module.
DSECT=: YES generates a DSECT for symbolic reference to the generated identification constants. If DSECT=YES, the LEVEL= and ID= parameters are ignored. Also, if DSECT=YES, BRANCH= must be NO.

Note: The IATYMOD macro expands inline. If you specify BRANCH=YES, the code expansion generates a branch around the identification statements. If you specify BRANCH=NO, no branch is generated. This could potentially cause an error if an attempt is made to execute the identification statements. Therefore, if you use BRANCH=NO, you should include a branch around the entire IATYMOD expansion before IATYMOD is issued.

If you omit all of the parameters on IATYMOD, the CSECT name is used for the ID= value, and the JES3 FMID is used for the LEVEL= value.
