[Coco] NitrOS9 Machine Language

[Bill Pierce]

I found most of the info in the Nitro Tech Ref... some more in the cgfx document.
One thing that I haven't seen explained though I probably just missed it, is does an "os9 I$Write" keep its pointers during succesive writes? In other words, if I want to load a GP buffer and can only get the data in pieces, will a loop of writes (ater the initial "$1b,$2b,grp,num ect".)  be incremented properly or will it have to done in one run. One example would be reading from a disk, 1 sector at a time then sending it via I$Wite to the buffer then getting another sector and so on. The whole idea here is to not set a large buffer space in the 64k workspace.

A lot of time was spent putting the documentation for NitrOS-9 on this wiki:
http://sourceforge.net/apps/mediawiki/nitros9/index.php?title=Main_Page
Specifically, you want the Technical Reference: http://sourceforge.net/apps/mediawiki/nitros9/index.php?title=NitrOS-9_Technical_Reference

ost explain the Basic09 and "C" usages. I know how to make the basic calls but 
an't seem to find info on stuff like, what regs to load for what parms. and 
uch. Example... the GPload, how do I tell OS9 where the data list is? I know 
ow to send the command string.. but where do I put the actual contents? It's 
ot just this call, but several others. I thought there used to be a good 
isting for M/L somewhere but can't remember where.
