Default group definitions

If no group definition changes were made to the Global Data Area, by default, OMEGAMON for CICS (3270) uses the first letter of the transaction IDs to assign all transactions to transaction groups 1–26.

Thus, transaction IDs beginning with A are assigned to Group 01 (TRAN=A*), those beginning with B are assigned to Group 02 (TRAN=B*), those beginning with C are assigned to Group 03 (TRAN=C*), and so on.
