OA66589: LOOP WHEN READING A NON-VSAM SEQUENTIAL DATASET ON A ZHPF DEVICE THAT DOES NOT HAVE AN EOF

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When using QSAM or BSAM to read a non-vsam physical sequential
  file that does not have an EOF marker, this may lead to tracks
  of data being read that do not fit the expected format of the
  dataset. This is because the data on these tracks is residual
  data.
  

Local fix

• If the file being processed is an empty file, you should be able
  to open it for output and then close it. This will cause an EOF
  marker to be written.
