[comp.sys.apollo] Undocumented fortran intrinsic functions?

juber@uceng.UC.EDU (james uber) (05/14/91)

Yesterday i was compiling some fortran code that needed an
error function.  By mistake, i forgot to include the library
that contains my error function code on the f77 command line.
I was surprised to see that there were no undefined externals.
Upon further investigation, i found that /usr/lib/libF77.a
has lots of stuff (error functions, bessel functions, ...)
that i didn't think it had, and that are definitly not
listed as either standard intrinsics or as apollo
extensions in the fortran manual (i just looked at output
from the "nm" command).

Are these codes documented somewhere?  I'm just wondering
cause they might be optimized for the apollo and thus 
perhaps better than my own.
