All AIPS tasks accept INNAME as 12 characters.  Unfortunately, the 
source name embedded in the header is limited to 8 characters.  I cannot 
even imagine how expensive it would be to change that - every data set 
and image on disk for every user would have to have a format revision, 
every aips file would have to be renamed etc etc This is not a good 
idea.  In fact the VLA now uses 16 characters (as in the source table) 
so even the 12 for INNAME is not adequate.  Again, changing that would 
be expensive and cause much user disruption (distribution versions would 
no longer be compatible among other things).

So the answer is no we cannot fix this.
