[Coco] C Programming

[Ron Bihler]

I am wanting to get back into programming on the Coco again.  It's been 
some time and I was mostly familiar with B09 and some ASM.  I had 
started to get into C at the time, but that was a very long time ago.  
In any event I was thinking to take on the challenge and do some work in 
C, I have the disk off of RTSI and started to look though them. 
Can someone recommend a good site or book to use a tutorial and one that 
is close enough to the OS9 C that it is relevant?
It's been so long without use that I am pretty much starting from 
scratch on relearning. 

Thanks
Ron
