I can't see what's wrong. You need
a trace, possibly.
Your code could be simplified using -forval- and
-foreach-, somewhat along the following
lines:
clear
set memory 512m
set more off
use "c:\data.dta"
foreach k in 1 14 27 40 {
forval j = 1 / `k' {
replace lfsocc`j' = 1 if lfsocc`j' == lfsocc`k'
replace lfsocc`j' = 0 if lfsocc`j' ~= 1
}
local l = `k' - 1
egen occten`k' = rsum(lfsocc1-lfsocc`l')
* n.b. `k' above
keep occten*
merge using "c:\data.dta"
drop _merge
}
