 NAME       : HCPLDFPL
 DESCRIPTION: Load file via FTP parameter list
 DSECT      : LDFPL
 FUNCTION   : Describe the parameters of a Diagnose 2C4 request
 LOCATED BY :
              Rx contains the logical address of the LDFPL in
              Guest storage at the time Diagnose 2C4 is issued.
 CREATED BY : The program issuing Diagnose 2C4
 DELETED BY : N/A
 RELOCATION CONSIDERATIONS : None
 COMMENTS   :
              The LDFPL is fetched by CP from the VM's storage
              during Diagnose 2C4 initialization.  An updated
              version may be stored in the virtual machine before
              Diagnose instruction processing completes.
