1.12 Expedited Program Change (EPC) Log
LANSA upgrades are issued as EPCs (Expedited Program Changes).
The steps required and any pre-requisite EPCs are supplied with each EPC.
If an EPC requires another EPC to be loaded first, the load process will check for the existence of previously required EPCs. If a pre-requisite EPC is not present, the EPC loading procedure will fail.
You can see which EPCs have already been loaded using the F10=EPC Log function on the screen. You access the screen using the ABOUT parameter on the 1.4 LANSA Command. The EPC details can be displayed in EPC Number or Date/Time sequence and can be printed.
