There you have, it despite setting the local macro max1 earlier in
your do-file, when it comes to executing the -forval- loop the local
macro is empty, so -forval- can't repeat something from 1 to
"nothing"!

However, you wrote that you have the following....

local max1=r(max)
gen error1=.
gen error2=.
*save `allsvys', replace /*OLD CODE: STATA 9*/
save "'allsvys'", replace

forvalues svy = 1/`max1' {
    use "'allsvys'", clear
    keep if i==`svy'
}


...which suggests that you are setting the local macro before the loop.

I suspect there may be some confusion from your full do-file error to
the shortened version snippet of code you have posted above where max1
is undefined.

So does...

local max1 = 2
forvalues svy = 1/`max1' {
         use `allsvys', clear
         keep if i==`svy'
}

...work?
