Re: LZ: Help with an interrupt
[Prev][Next][Index][Thread]
I'm not gonna explain it all here, but there are two cool documents from
ticalc.org you can lok at. In the zshell programs directory, the is a
file called itest.zip. Get it. Even though the program was written for
zshell 3.0, the document by Per Finander is good. Also, if you want to
see interrupt code, 4gray.txt, even though the title has nothing to do
with it, shows how to install an inteuuppt into the graph mem. At least
these two things helped me learn interuppts. Have Fun, and then ask
list-zshell any small questions or problems you have.
