A CA Ideal batch job gets the following error:
IDADCMDP02E - Command invalid or incomplete starting at "SIGNON"
This error is usually returned when CA Ideal is running with External Security activated for signon (SECRTY=Y in SC00OPTS)
To determine the current setting for SC00OPTS in the CUSLIB, run DBCGSPR to generate the source from the SC00OPTS load module.
If SECRTY parameter is set to Y in SC00OPTS, then the SIGNON card is no longer required, so it must be removed.
Enabling External Security section of Ideal documentation states:
The CA Ideal™ for CA Datacom® SIGNON statement no longer determines the identity of a batch user since the user ID is passed to the external security package in the JCL. .
