	Hello again,

	Another unrelated question for you all.  I'm trying to build some 
fortran packages, and I was having some linking errors.  So I looked in the
archived library where the funcions are supposed to be.  And the functions
were there, except they had an underscore ( _ ) after the function name.  So
I looked on a SGI machine and a DEC machine, they all had the underscore. 
Except on these machines the package was built with no problem.  And I looked
on the machine (DEC) that had the sources to some of the math fortran
libraries, and, in the comments, they showedthe function name with a underscore
and how it should be called from fortran.  The call was WITHOUT the underscore?
Does the fortran compiler (on some machines) append the underscore to the call?
What is the purpose of the underscore - to distinguish between <C-function> 
and <FORTRAN-equivalent-C-Function>_ ????


	Any clues ???  Thanks alot, Greg
