Urgent Software Advice Needed

[Andrew W. Hill]

Okay, so I'm sitting here on my 2400 happily on holidays, when 
suddenly I'm asked for my contribution for a college reader.  What I 
need to do is those programming flow charts.  You know the "is it 
broken/did you mess with it/you stupid git" style stuff.  Yeah, so I 
need a program for os9 that I can make one on.  Theyre real simple 
code snippets, like 10-20 lines in C-style pseudocode.  It needs to 
be something I can download tonight, or perhaps early tomorrow. 
Needs to follow ANSI etc.
Please respond offlist as a) this is offtopic and b) I gotta get this 
done quick and i dont always see all my list maikl
Thanks guys, and sorry for the OT
