Paul,

The files in sglib.tar.Z are for the "SGLIB: The Scientific Graphics
Library", by Marilee E. Thompson, et.al. To use these files on a unix
machine, type:

uncompress sglib.tar.Z
tar xvf sglib.tar

and read the files in sglib, particularly sglib/README.  Marilee tells me
that the code compiles and runs well on a lot of unix machines: SUN, SGI,
DECstations, DEC alpha workstations, etc. However, at least one previous
version of the CRAY compiler had difficuly with lines of the form:

	do i=1,n
		....
		if(...) go to 10
		...
   10	enddo

In order to get it to work, the last line would have to be replaced by

   10	continue
	enddo

Maybe more recent CRAY compilers (particularly the new fortran-90?) won't
have this problem?

Good luck.
