st: Running glm with user-written link function in a program without a separate ado file?

[Aspen Chen <aspen.chen@uconn.edu>]

Dear fellow Stata users,

I have been writing a program (an ado file) that runs a glm estimate
with a user-written link function. The program can run successfully
when the link function is stored as a separate ado file. But I would
like to keep the entire program as one single ado file for simplicity
sake if possible. Does someone know if there is a way to accomplish
it?

If it helps illustrate the issue, here is an outline of what I've
tried so far to no avail. First, I kept the link function as a
subroutine in the main program as below, but the glm failed to find
the link function.

program main_program
[...]
glm [...], l(mylink) [...]
end

program mylink
[...]
end

I then thought perhaps rewriting the glm as another subroutine would
help it find the link function. This approach has worked at times but
not consistently (not exactly sure why).

program main_program
[...]
myglm [varlist]
end

program mylink
[...]
end

program myglm
syntax varlist
glm `varlist', l(mylink) [...]
end


Thanks for going through my question. Any input is appreciated.

Regards,
Aspen
