C-Graph is a package of five simple core functions reproduced in C
from my Honours thesis "Interactive Computer Package Demonstrating:
Sampling Convolution and the FFT", University of Aberdeen, Scotland
(1983). Use C-Graph to generate signals for work or play.

C-Graph is free as in beer!

In recplot.c, line 42 you have initgraph(&driver, &mode, "c:\\adrienne\
\tc\\bgi");
If I understand correctly that's a hardcoded path. I hope you don't
expect your code to work anywhere else other than your own comp.
Moreover, this is comp.lang.c, we discuss ANSI/ISO C and I believe
topical.

any technical modifications necessary to run the code. The code is
ancient, remember - 1996. As I indicated in the documentation, I
haven't updated or upgraded the files since the day I created them.

It's not about advertising, I thought engineers coding in C might find
the functions useful - and fun. Hopefully comp.lang.c will inspire me
to reactivate my C programming.

Yes, it's from 1996. See the post above. Enjoy!

FYI a sig. marker is the specific line "-- ", with the final space,
and nothing else (no quotes). It marks everything from that point
on as being part of the sig.

Thanks for the information. I've been marooned on Caprica for a couple

I got a couple of emails signed like that, i.e. "--sig". Thought it
was cute

Enjoy the code - and 2009!

Your sig marker is still missing the critical final blank.

Hi CB:

My modem is broken on GNU/Linux for the moment so I've been panefully
using Notepad to write and edit my messages.

I'm pretty sure I inserted a final space after the "--". I'll insert
the blank this time directly in my browser. This any better?

Thanks; this is very patient of you. I'm more than puzzled. That final
space is a bit like the University of Aberdeen's ghost -
http://www.codeartnow.com/law-project/boo.

They can't say who wrote the FORTRAN program in my Honours Thesis,
just that it couldn't be me.

I'll get back to you on the sig marker.
