```Dear Amani,
Here is a suggestion. Hope it helps.
best regards,
jean

local X 43

forvalues Y = 120(10)530 {
predict prob`Y', pr0(`Y',`Y+10')
predict exp`Y', e0(`Y',`Y+10')
replace prob=prob`Y' in `samp-`X''
replace exp=exp`Y' in `samp-`X''
loc X = `X' - 1
}

```Dear Stata-listers,

I wish to make two "forvalues" loops work together rather than nested as
shown by my suggested code below.  Is there a way I can do that in STATA

local samp=_N+43
set obs `samp'
foreach M of newlist prob exp {
gen `M'=.
}
intreg ptiming timing if ~npointer1, noskip intreg
forvalues Y = 120(10)530 ;  X = 43(-1)1 {
predict prob`Y', pr0(`Y',`Y+10')
predict exp`Y', e0(`Y',`Y+10')
replace prob=prob`Y' in `samp-`X''
replace exp=exp`Y' in `samp-`X''
}
local samp=_N-43
slist prob exp in `samp'/l
