APAR status

• Closed as program error.

Error description

• Application doing a fread() from tape. The POINT macro call in
  CEL4IO31 branches into middle of a instruction at x'10' into
  IGG019BD module resulting in a 0C4.
  
  Additional Symptom: 0C1 at x'10' into IGG019BL due to bad
  branch from LE/C library on application call to fread() from
  tape.
