IBM has changed their Fortran since we last owned an IBM workstation.
It now returns an error code 1 for end of file.  In 31DEC01 I have
repaired this and issues about files > 2 Gbytes in size by converting
all FITS disk I/O to C.  But for 31DEC00 there is a problem.  I
suggestthatyou cut out the file attached below and do the following:

1. Copy the file to $APLIBM/ZTPWAD.FOR
2. COMRPL $APLIBM/ZTPWAD
3. COMLNK $APGNOT/FITLD
4. test it.
5. If it works then

COMLNK $AIPPGM/AIPS
COMLNK $AIPNOT/TPMON
COMLNK $AIPNOT/GRITP
COMLNK $AIPNOT/GR2TEX
COMLNK $APLPGM/PRTTP
COMLNK $APLPGM/AVTP
COMLNK $APLPGM/TCOPY
COMLNK $APGNOT/BAKLD
COMLNK $APGNOT/BAKTP
COMLNK $APGNOT/FILLM
COMLNK $APGNOT/FILLR
COMLNK $APGNOT/FITTP
COMLNK $APGNOT/GSCAT
COMLNK $APGNOT/IMLOD
COMLNK $APGNOT/MK3IN
COMLNK $APGNOT/MK3TX
COMLNK $APGNOT/UVLOD
COMLNK $APGNOT/M3TAR

C   Inputs:
C      FCB    I(*)   File control block for opened pseudo-tape disk file
C   Output:
C      IERR   I      Error return code: 0 => no error
C                       3 => I/O error
C                       4 => end of file
C                       7 => wait service error
C   NOTE: EOFERR value will vary between systems.  If synchronous I/O,
C   no need to wait.
