Your FITS file is a file not in AIPS internal format.  It should reside 
somewhere on your disk system.  I keep mine in a special area 
/home/primate2/PRIMATE_1/FITS
with an environment variable (MYFITS) that points at it.  Then
datain='MYFITS:xxx
where there is no close quote on the string so that case is preserved 
and xxx is the name of the file in my area.  NOte that that area should 
not be DA01 which is where data in AIPS internal format are stored.
Case is significant in the value of DATAIN and the first try says that 
it can translate $DA01 but that there are no files named 
PKS1136+POL_I.FITS1
in that area with or without the trailing 1.  The other two say that 
there is no translation for $da01.  You must get DATAIN correct to load 
a disk FITS file.
