How to jump out a forvalue loop after finding a specific value ?

[IHSEIN LEE]

cd "C:\Users\GagaLee\Desktop\ga"
local ff : dir . files "*.dta"
dis `"`ff'"'

mat ga=J(48,2,.)
local x=1
foreach i of local ff {
use `i'
local N=_N
forvalue a=1(1)`N'{
sum vo2_2 if inrange(_n,`a',(`a'+30))
local xxx=r(sd)/r(mean)
mat ga[`x',1]=`a' if inrange(`xxx',0,0.15)
mat ga[`x',2]=r(mean) if inrange(`xxx',0,0.15)
if inrange(`xxx',0,0.15) break
}
local ++x
}

See -help continue-

A simple example:

sysuse auto,clear
forv i = 1/5 {
    disp "Current i value = " `i'
    dis mpg[`i']
    if inrange(mpg[`i'], 19,20) ==1  {
        continue,break
    }
}

I have tried this but still in vain ...


----------------------------------------
cd "C:\Users\GagaLee\Desktop\123"
local ff : dir . files "*.dta"
dis `"`ff'"'

mat ga=J(48,3,.)
local x=1

foreach i of local ff {
use `i'
local N=_N
forvalue a=1/(`N'-30){
sum vo2_2 if inrange(_n,`a',(`a'+30))
local xxx=r(sd)/r(mean)
if `xxx'< 0.15
{
mat ga[`x',2]=`a'
mat ga[`x',3]=r(mean)
continue, break
}
}
local outfile = substr("`i'",1,2)
mat ga[`x',1]=`outfile'
local ++x
clear
}
-------------------------------------

invalid syntax
r(198);

I have found the bug. Sincerely thank you for your reply!
