IMS command codes

Restriction: This topic applies only when the AppMaster Builder AddPack has been installed, and applies only to Windows platforms.

Use the CCODE keyword to include additional IMS command codes in DB-OBTAIN, DB-MODIFY, DB-PROCESS, and DB-STORE. Most IMS command codes are generated by the call keywords; any command code you specify with the CCODE keyword is added to these.

Note: Use CCODE carefully, because the command codes you specify with it are not validated by the IMS DB Generator.

Valid IMS CCODEs are:

P	Establish parentage at this level.
Q	Enqueue the segment.
U	Maintain current position at this level.
-	Null command code.

AMB generates the following IMS CCODEs; do not code them yourself.

D	Put segment in I/O area (generated by REC).
F	Locate first occurrence (generated by FIRST).
L	Locate last occurrence (generated by LAST).
N	Do not replace segment (generated by REF).
V	Maintain current position at this level (generated by CURRENT).

For more information, refer to the applicable IMS manuals.
