     NAME       : IPARMLX
     DESCRIPTION: APPC CONNECT PLIST EXTENSION MAPPING
     DSECT      : IPARMLX
     FUNCTION   : TO MAP THE CONNECT PARAMETER LIST EXTENSION
                  PROVIDED ON AN APPCVM CONNECT WHEN FMH5=NO
                  IS SPECIFIED.
     LOCATED BY : MAINTAINED IN CP STORAGE IN THE CONBK.
     CREATED BY : USER VIRTUAL MACHINE
                  HCPIUR (AS PART OF THE CONBK)
     DELETED BY : HCPIUR (AS PART OF THE CONBK)
                  HCPIUQ (AS PART OF THE CONBK)
     NOTES      : ANY CHANGES TO IPARMLX COPY SHOULD ALSO BE MADE IN
                  THE INTERNAL CMS VERSION, DMSIPMXP, TO KEEP THE
                  MAPPING IN SYNC BETWEEN CP AND CMS.  THE CMS
                  BILINGUAL MACRO, DMSIPMX, USES THE ASSEMBLER COPY
                  FUNCTION TO INCLUDE IPARMLX COPY WHEN INVOKED FROM
                  AN ASSEMBLER MODULE.
