APAR status

• Closed as program error.

Error description

• After a Receive Any RPL request is rejected by VTAM
  module DFHZRAC program checks AbendS0C4
  at +BE8 in label ZRACDMGM.
  The problem is a branch from within label ZRACR6A
  ( unber label TCZRACR6 ) where a BAL to label ZRACDMGM
  skips past a new base register set up for the GETMAIN.

  R:5  00120  USING DFHZRAC1,R5  resolve GETMAIN addr
  .
  The USING gets processed at compile time,
  but the LOAD (L) is missed at run time.
  So, register 5 is not initialized before the GETMAIN macro.
  The macro expands to include parameters
  and provides a label (IHB0674F) to point at them.
  Then, it tries to load register 15 with a pointer to that label
  .

  A RECEIVE ANY call in DFHZRAC fails with a non-zero return code
  in register 15.  The CICS region abends U1800 with dump code
  SR0601.  The dump shows an S0C4 abend in program DFHZRAC
  on a LOAD instruction with register 5 all zeros.
  The error is in a routine to GETMAIN some storage for an
  error message.

Problem conclusion

• The routine ZRACDMGM has been changed to correctly establish
  addressability using register 5 for the LOAD instruction.
