When the required name and the optional name (ACBNAME) are defined

The following model application program definitions contain an optional name defined on the ACBNAME operand:

NET?NAME  APPL  ACBNAME=WILD?,AUTH=(PASS,ACQ),EAS=5,…
 
NET*NM    APPL  ACBNAME=WILD*,AUTH=(PASS,ACQ),EAS=1,…
 
NET?NAM?  APPL  ACBNAME=WILD??,AUTH=(PASS,ACQ),EAS=6,…

The OPEN macroinstruction, OPENXYZ, specifies that the application program associated with ACB123 requests to open its ACB, as follows:

OPENXYZ  OPEN  ACB123
ACB123   ACB   AM=VTAM,APPLID=WILD1,…

The ACB macroinstruction, ACB123, requests to be associated with the definition of application program, WILD1. VTAM® cannot find a definition for WILD1 in VTAMLST, but it does find a name, specified on the ACBNAME operand, that best matches WILD1, and that is WILD?. The ? in WILD? is replaced with 1, as is the ? in NET?NAME. Therefore, the optional name of the application program is WILD1 and the required name is NET1NAME.

If the name specified on the APPLID operand on the ACB macroinstruction was WILDONE, VTAM would use WILD* as the model application program definition. The optional name would be WILDONE and the required name would be NETONENM.

If the name specified on the APPLID operand on the ACB macroinstruction was WILD1S, VTAM would use WILD?? as the model application program definition. The optional name would be WILD1S and the required name would be NET1NAMS.
