Re: st: simulataneous foreach loops

[Nick Winter <nwinter@virginia.edu>]

It sounds like you want something that the old, 
out-of-date-and-no-longer-supported -for- command made easy:

for num 101 102 103 \ num 3 5 3 : di "team X will have Y members"

-for- is no longer documented, so you'll have to guess how to use it if 
you want something more complicated than that.

In modern Stata, you could do something like:

local tnums 101 102 103
local tsizes 3 5 3

forval i=1/3 {
  local team : word `i' of `tnums'
  local size : word `i' of `tsizes'
  di "Team `team' will have `size' members"
}

The loop right now creates team 101 with 3 members, team 102 with 5 members, team 103 with 3 members, etc. Yes, there's a one-to-one mapping from tt to NN. I basically need two loop indices to change simultaneously. For example, first round (i=103, j=3), second round (i=139, j=5), third round (i=230, j=3). Of course, the real thing is a couple hundred pairs.
