interface blocks

I have about 3500 subroutines with 400,000 lines of f66/f77 that I am
porting to use IVF 9.0. I am considering building a generic interface
block with all 3500 subroutines in order to ensure that we are not
having argument problems (number of and/or data type). I have been
told that this might be a bad idea. Why ?

Thanks,
Lynn
