IPARMLX Prolog

 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.
