foreach v of local lvstk {
egen `v'nbeg = sum(liv_begnum) if `v', by(houscode qtr)
egen `v'nend = sum(liv_endnum) if `v', by(houscode qtr)
local lvstknos "`lvstknos' `v'nbeg `v'nend"
}
Hope this helps,
Maarten
NB notice the absence of the equal sign in the local
statement, this will protect you against strings that
are too long.

Subject: st: new local macro from results of loop
Dear list
I define a local macro lvstk below which contains variables I would like to process further. For example
local lvstk "cattle largeanims calves smallrums smallanims"
foreach v of local lvstk {
egen `v'nbeg = sum(liv_begnum) if `v', by(houscode qtr)
egen `v'nend = sum(liv_endnum) if `v', by(houscode qtr)
}
how do I automatically put the new variables being generated into a new macro
say
local lvstknos "cattlenbeg cattlenend ....and-all-the-other-stuff-coming-out-of-the-foreach-loop"
Ronnie
