Is it necessary for the X's to be global macros?
Why not make them locals as well:
local X2 "age2 weight2 height2"
local X3 "age3 weight3 height3"
...
local X11 "age11 weight11 height11"

and then:
forvalues n = 1/10 {
	local p = `n' + 1
	reg y`n' `X`p''
}	

regards,
Kris

Subject: st: local variable within a global macro?

Dear list-members, 

I have a small (or so it seems) problem with a loop (shown
below).  

I start by generating a few global macros:
global X2 "age2 weight2 height2"
global X3 "age3 weight3 height3"
...
global X11 "age11 weight11 height11"

Then I try to run the following set of regressions using a
loop:
forvalues n = 1/10 {
	local p = `n' + 1
	reg y`n' $X`p'
}

However, this isn't executed due to an error that says "2
invalid name" (i.e., it's referring to some problem in the
way I have used `p' in $X`p'.)

Could anyone please tell me what would be the correct way
to do this?  

Thank you very much for your help.

Nishant
