 NAME       : HCPSDPL
 DESCRIPTION: SNAP DATA PARAMETER LIST
 DSECT      : SDPL
 FUNCTION   : A SDPL LIST IS BUILT BY A CP MODULE WHICH ISSUES A
              A SOFT ABEND TO INDICATE ADDITIONAL DATA AREA(S)
              TO BE PRESERVED IN THE SOFT ABEND DUMP.
 LOCATED BY : BY REGISTER 1 FROM THE HCPABEND MACRO
 CREATED BY : THE CALLER OF THE SOFT ABEND PROCESSOR
 DELETED BY : THE CALLER OF THE SOFT ABEND PROCESSOR
 SERIALIZED : THE CALLER
 RELOCATION CONSIDERATIONS : None
