I don't know the answer to that in detail - I had a login, but I never
had to do any maintenance work on the 36-bit hosts when I was there,
but from what I can gather, CompuServe didn't write their tools in
standard FORTRAN - they had an extended FORTRAN compiler they called
XF4.  There were also lots of home-grown libraries, and AFAIK, hooks
into the OS to make writing local utilities easier and more powerful.

operators were invoking a system of custom-written utilities one after
the other for anything more complicated than DIRECTORY.

Here's a link to some company history written in 1988...
