Hi all,

I am a neophyte of CAL and IL and just study it for a few days. I read the IL spec and found the IL doc seems to be incompleted, and I always can not find what I need in the doc. 

for example:

the syntax for input register declaration instruction is

dcl_input[_usage(usage)] dst[.mask]

buf I don't know what value the usage should be taken and there are no information about it in the IL spec.

so I doubt that there may be some other docs to be referred to when studying CAL and IL, is that right ? and what are them and where can I find them?
