 NAME       : HCPFTPBK
 DESCRIPTION: FOOT-PRINT BLOCK
 DSECT      : FTPBK
 FUNCTION   : PROVIDE FOOT-PRINTING OF THE RECOVERY
              PROCESS FOR SUBSEQUENT DEBUGGING
 LOCATED BY : HCPWRKFP IS THE ANCHOR FOR THIS BLOCK.
 CREATED BY : THE ASSEMBLY OF HCPWRK.  THE
              FOOT-PRINT BLOCK ALWAYS REMAINS
              IN THE HOST CONTROL PROGRAM CRITICAL
              WORKAREA.  EACH OF THE FOLLOWING
              MODULES 'OWN' AN AREA IN FTPBK
              WHICH THEY USE FOR RECORDING :
              HCPVRWCD
              HCPVRRLD
              HCPVRTST
              HCPVRRMS
              HCPMCWMD
              HCPVRV
              HCPWRP
              HCPDMP
              HCPVRE
              HCPCKP/HCPWRM
 DELETED BY : NONE, HOWEVER THE BLOCK IS CLEARED
