Too many variables in loop

[samaneh khaef]

Hello
I am using the loop function for some simple merges of 5 datasets.
I did it before and it worked. now to redo it again I faced with" too many variables defined" error. Does anyone help me?
my syntax is:

forvalues loop=2002/2016{

clear

use "\\...................\F`loop'.dta",

gen local z=`loop'-1

merge 1:1 Id using "\\..................\G`z'.dta"

keep if _merge==3

drop _merge

save "\\...........................\Cohort`z'.dta", replace

}

[CODE]
gen local z=`loop'-1
[/CODE

is wrong. Cut the gen

Ahaaa. apparently, someone changed it that is why I did not notice!!! Thanks a lot

No idea what that means. Someone else broke your code?

Not here! I am working through a shared platform. So it is common to use other codes sometimes. but this time my colleague made some changes and by mistake save on my folder. that is why I said it worked before and now it did not. Thanks for help

The code in #1 should never have worked at all.
