#### IPARML Prolog

     Name       : IPARML
     Description: IUCV/APPC parameter list and external
                  interrupt mapping DSECT.
     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.
