We have made a lot of changes to our f77 compiler over the last year
or so. Would somebody like to run the small program below and let
me know if they get a 
`compiler error illegal tag 0'
error message? Or have we screwed up an edit somewhere. 


The program is actually illegal - I think a good compiler should
pick up the illegal redefinition of MAXLEN as a constant.

Thanks,
