alias, procedures, macros

[Germain G. Ivanoff-Trinadtzaty]

Hi,

I want to define new commands (without arguments):
\sansbis : would be an exact alias to the call \sans
\myfont : would be a modified version of \sans

I can't figure out the way to define these, though I've read a couple of 
sheme snippets.

Any idea ?

Thanks,
Germain
