Actually, some times it isn't worth it. For movie (v5.2), there are
hundreds of subroutines. After fsplit'ing and creating a makefile, I 
have found that up to 5 min cpu time (on 68k's) can be spent by make
checking update times of file. There is a lot of disk traffic associated
with this. It would be nicer to break the source into fewer,logically grouped
subroutines/functions as we *ALL* do with C source files. Unfortunately,
we can't do this with f77 as we either run out of memory or page the
system to death (dep. on which sys). Some programs also have VERY large
subroutines (someone else's code *of course*). Sometimes these can't be 
compiled under f77!!
