What you describe below creates variables equal to constants, which is not a good idea in Stata. If you want to have a set of scalar values taking on specific values, use the scalar command in Stata. You can, as others have suggested, do something similar with matrix elements in Mata (which, like Stata, is not an acronym). You can also use Mata pointers to create a set of temporary variables in Mata.

Is there anyway of dynamically generating variable names in MATA?

For example, I would like to be able to write something like this:

count = 10

for(x=1; x<=count; x++) {

y = strofreal(x)

hello_`y' = x*10

}

and is this way generate 10 variables named hello_1, hello_2, ... hello_10.

I know that the STATA local ` ' syntax doesn't work in MATA, but it

would be very very helpful to me to be able to be able to dynamically

generate variables in MATA.

If there isn't anyway of dynamically generating variables in MATA, are

there any work arounds you suggest?
