Hi Ben,
Sorry to dig out this old post ...
This was about how to set up some code resources in CodeWarrior,
you said that I could have a look at DemoHack to see how to setup a .r file
to pull my code in the main application.
But I don't really see how to do that with the .r file included in DemoHack,
which is the following :
include "patc1000.tmp";
include "patc1001.tmp";
type 'tAIN' {
align word;
cstring; // name
};
type 'TRAP' {
hex integer; // trap number
};
resource 'tAIN' (3000) {
"It's DemoHack!"
};
resource 'TRAP' (1000) {
0xA171
};
resource 'TRAP' (1001) {
0xA191
};
Do I have to use the same kind of syntax to pull the code resource in my
main application ?
how do I do that ? (there's not a lot of documentation on Rez)
