IPARML Prolog
Name : IPARML
Description: IUCV/APPC parameter list and external
interrupt mapping DSECT.
STATUS : VM/ESA Version 2, Release 3.0
DSECT : IPARML
Function : To map the parameter list used when an IUCV or
APPC/VM function is issued, and to map the
external interrupt buffer when an IUCV or APPC/VM
external interrupt is reflected to a virtual
machine or a CP System Service.
Located by : Parameter list address is specified by a user
virtual machine.
External interrupt is specified by the user
virtual machine and maintained in IUCBFAD1
IUCBFAD2 fields in HCPIUCVB.
Created by : User virtual machine:
-Parameter list passed on most IUCV functions.
Deleted by : User virtual machine.
NOTES : ANY CHANGES TO IPARML COPY SHOULD ALSO BE MADE IN THE
INTERNAL CMS VERSION, DMSIPMLP, TO KEEP THE MAPPING IN
SYNC BETWEEN CP AND CMS. THE CMS BILINGUAL MACRO,
DMSIPML, USES THE ASSEMBLER COPY FUNCTION TO INCLUDE
IPARML COPY WHEN INVOKED FROM AN ASSEMBLER MODULE.
