You can pass options to your second program the same way you would to
your main program:
prog testsub
syntax varlist(numeric) [, mod2(varlist)]
sub `varlist', mod2(`mod2')
di "sub reports varlist (`mod2') forms " r(N) " groups"
end
prog sub, rclass
syntax varlist(numeric) [, mod2(varlist)]
tempvar g
qui egen `g'=group(`mod2')
qui tab `g'
ret scalar N= `=r(r)'
end
sysuse auto
testsub mpg, mod2(rep78)
tab rep78
testsub mpg, mod2(for rep78)
tab for rep78
Remember locals can only be seen within the program or do-file where
they are defined, and Statalist members can only comment on examples
using data that is easily available to all copies of Stata.

Austin,
I'm not sure if it's proper etiquette to reply individually but it

Yes, I believe I am trying to do exactly what you described, and I took
a look through the manual and the example you pointed out. But I'm
still not 100% sure how to pass on arguments (or maybe I am and should
just try it).
So from my example how would I pass on `varlist' (coming from syntax in
master program) and `mod2' (from the options in syntax in master
program) macros to the subprogram (-spreadprog) from the master program.
Here's what I derived and if it's correct no need for a full reply. If
I save the programs together in the same .ado file, then when I call to
`varlist' and/or `mod2' will it recognize/use them from the master
program. [I tried to do just this but I was only working in .do files.
So will the transfer to .ado make the difference here?]
Thank you for all of your help, it is truly appreciated,
Kyle
Quoting Austin Nichols <[email protected]>:
Kyle--
Do I understand that you are trying to define a -program- within the
definition of another program in a -program- -end- block? The right
way to program is to write a bunch of separate programs, save them to
a file called something.ado, and to pass parameters from one program
to another as appropriate using -args- or -syntax- or the like. See
the [P] manual and have a look at a good example:
. viewsource ivreg.ado
