PK82002: EGLPREP - CONCURRENT BUILD ON ZOS SOMETIMES FAIL

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When EGLPREP Is used with multiple threads, for builds involving
  cobol compiles on host, a problem may occur as multiple host jo
  bs will try to write to the same cobol pds.
  This should normally have been by fixed by adding ENQ=YES keywor
  d, but
  the ENQ=YES keyword on the ddname for the input files in the bui
  ld scripts is being ignored, so
  ENQ=YES
