There are two solutions. First you can refer to the returned result as
`r(numd)' like in the example below:

*--------- begin example ----------
capture program drop cu7
program cu7, rclass
local numd 1
return local numd =`numd'
end
cu7
if `r(numd)' == 1 {
	di "bla"
}
*---------- end example -----------

Second you can return numd as a scalar instead of a local, like in the
example below:

*--------- begin example ----------
capture program drop cu7
program cu7, rclass
local numd 1
return scalar numd =`numd'
end
cu7
if r(numd) == 1 {
	di "bla"
}
*--------- end example -------------

Hope this helps,
Maarten
