Well I read it, and Mr President Bill G addresses some of those
questions (like how to organize cycles with variables in Mata rather
than with macros in Stata, and how to deal with string literals in
Mata). But it looks that in my particular case, where I have
repetitive execution time substitutions of the file name, I would
really need to go back to Stata to achieve exactly what I want (to
have a .mmat name of my choosing). At any rate, the occasion I needed
that for was in simulations, so I am switching between Stata and Mata
a few times, and won't be bothered switching to Stata in the end to
save my simulation results:

args simulation parameters
local thenameIwant simul-`simulation'-`parameters'
mata:
// simulations
end
mata : mata matsave `thenameIwant' All Those Matrices
exit
