it is always an option to change inlist parameters from your run_star_extras routines.
all of the &controls parameters are defined in the star_info structure, so s% xtra_coef_b_l_nb_czb = 0.5 has the same effect as setting it in the inlist.
the &star_job controls are also accessible, but keep in mind that they are defined inside a substructure of star_info called "job".
so from your code you'd write something like s% job% pgstar_flag = .true.

The parameters will be used during the remesh, and that happens at the start of the step.
'other_mixing' is called after the remesh, so that's not what you want (at least not if you want the change to happen for the current step).
by 'other_mesh' I assume you mean 'how_many_other_mesh_fcns' and 'other_mesh_fcn_data' -- they are called when 'use_other_mesh_functions' is true.   you could set the mesh parameters from either of those.

The easiest thing would be to set them in extras_finish_step so you don't need to use a hook -- they'll take effect with the next step.  


Good luck,
Bill
