User exit routine UCCFLM is invoked from the fast link macro decoder if the
FLM exit point is
active. Exit point FLM is in CSECT CCNUCL.
General Conditions at Entry
The registers at entry to UCCFLM are:
- R6
- Address of the macro entry in the macro decoder table.
- R8
- Base of E-type program that issued the fast link macro.
- R9
- Address of the ECB.
- R11-R15
- See User Exit Routines - Common Entry Conditions.
System Conditions at Entry
- System state
- Problem (see Programming Considerations at Entry, item 2)
- System mask
- Unmasked (see Programming Considerations at Entry, item 2)
- Protect key
- Working storage
- Address Space
- EVM.
Programming Considerations at Entry
- The contents of program registers R0-R7 have been saved in the ECB
register save area.
- Usually, the system state and system mask are as
stated. However, there can be exceptions if system programs issued
MONTC to get to supervisor state and changed the system conditions.
- This exit includes ENTRC to FACE or FACS.
- The FLM exit point occurs before formatting an entry in the macro trace
table.
- See User Exit Routines - Common Programming Considerations for other considerations.
