Re: [Pycrc-users] type mismatches solved

[C. M. <cm...@gm...>]

Thanks for your quick response.  I am out of the office today but will
send my command line and output files tomorrow or Monday.  I did
specify individual parameters on the command line and generated
separate c and h files -- no main().

BTW, I took a quick look at the py files.  Wow.  A whole macro
language.  Impressive.

Thanks!
