Definition of some functions and variables

I’m studying this mod file, but I find that some functions and variables in it can’t be found in the manual, such as m_ maximum_ lag、simult_ wait. I want to ask if there is a file that contains the introduction of all functions and variables of dynare.

M_.maximum_lags stores the maximum number of lags in Dynare’s internal representation and therefore indicates when the actual simulations start.
The simult_-functions header is explained at matlab/simult_.m · master · Dynare / dynare · GitLab
