PI37689: MODIFY IGZXAPI TO DETECT WHEN GARBAGE IS PASSED TO IT OR A STORAGE OVERLAY EXISTS

Obtain the fix for this APAR.

APAR status

• Closed as new function.

Error description

• (COB V5.1) Modify IGZXAPI to detect when garbage is passed to
  it or a storage overlay exists.
  
  An ESPIE will be used, but only when control is inside IGZXAPI.
  On entry, IGZXAPI invokes ESPIE and remembers the previous
  token.  When IGZXAPI returns, it invokes ESPIE RESET and
  restores the previous token.  Other than this, IGZXAPI doesn't
  register any ESTAE or recovery routines. This should not affect
  the use of ESTAE in IGZXAPI's caller.

  IGZXAPI needs the caller to provide the user's COBOL program's
  DSA. When the provided pointer is invalid, IGZXAPI may ABEND.
