Subject   st: using the same macro in program & mata

Hi,

I am writing a program that calls Mata and then, within Mata, calls a Stata command. Currently, what I have written to do this looks something like:

program name
global depvar `1'
mata : temp_("$depvar")
.....
mata:
void temp_(string scalar dep)
{
....
stata("reg $depvar xvar")
....
}
....

The program does what I would like, however, I read in the Stata Manual ([U]18.3.10) that one should never use global macros when a local macro will do the job. Because I will be using this command (name) in conjunction with other programs and sharing it with others, I would like to avoid any possible adverse effects of using the global macro. Is there a way to define this variable (depvar) as a local macro?

Thanks for your consideration,
Maria
