NTRY | You can list explicit data areas; this allows flexibility in passing data areas between programs. |
TP-COMMAREA | Not required to pass data areas between programs, but is supported for upward compatibility. |
SEND | Provided for upward compatibility; does not invoke a program. Use LINK to invoke a program that displays a screen. |
TP-LINKAGE | Provided for upward compatibility. This call is necessary for CICS to order the LINKAGE section properly, but DLG lets you locate user records in LINKAGE without coding TP-LINKAGE. |
The PFKEY option allows PF key processing similar to AMB CICS and IMS with the Program-Controlled option when converting a AMB CICS or IMS application to DLG.
