CA IDMS Tuesday Tip from Ian Hill, Principal Support Engineer for October 29, 2014
There are times when you may need to know the meaning of an IDMS verb number also known as a function code. For example JREPORT-008 will list verb numbers. These are different from the IDMS major code.
You can find the verb numbers documented in the DML Reference Guide for COBOL, Appendix D.2 in the section DB Call Formats. The numbers in the IDBMSCOM(nn) column are the IDMS verb numbers. For example a MODIFY DML command has a major code of 8 but its verb number is 35.
