  ****************************************************************
  When running the CICS web sample program under CEDX and the CICS
  region has storage protection active, a change to the data being
  sent out will result in an 0C4 in DFHEDFD. The CICS web sample
  program, DFH$WB1A has storage defined as a constant, which when
  the attempt to change this storage will result in the abend
  because the storage is in the ERDSA.
