[Coco] FW: [Non-DoD Source] Coco Digest, Vol 173, Issue 31

[Taylor, Phillip L CIV]

A long time ago in the 90's I wrote a small word process and the X and Y are 
used as pointers and the A register is used to load the value and used with 
other instructions like bne and beq.

I do not see how in the examples you can use a as a pointer for the location.

 Thanks


Your best bet probably is to study the source code for attr in the NitrOS-9 
project. The code is not very simple but once a file is opened, SS.FD & 
I$GetStt read the attributes while SS.FD & I$SetStt set the attributes. That's 
over simplification so good luck. :)

I read the manual but I am unable to figure out how to point A to the file 
name /dd/cmds/test.  I learn better if I can see some example code please?

When I read this I though, there must be a typo in the manual. OS-9 would 
never use reg A as a pointer.

Then I read the manual and it says reg A is loaded with the path number.

The path number is what is returned by I$Open or I$Create.
