     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.
