st: skipping out of and restarting a loop if an error occurs

["Ben Hoen" <bhoen@lbl.gov>]

I am trying to loop through txt files of New York counties (9 of them) and
years (2000-2012) for which some year/county combinations are missing.  For
each file I am using insheet and then, once loaded I perform some additional
commands and the append it with the previously loaded file.  

The files are named using their respective year county, e.g, "<county
name>_<year>_parcel.txt"

I have been able to use .capture noisily to skip the unsuccessful .insheet
command, but have not been able to find a way to skip the rest of the loop's
commands and start at the top.  (I thought it might involve the "_rc" stored
value and "continue" ... but was not able to figure out how to do that) 

Any help would be much appreciated.  Thanks in advance.

Here is some sample code:

==============================================================
clear all
tempfile newparcel combinedyr combinedco
g testvar=. //to create some data to initially store
save "`combinedco'"
save "`combinedyr'"

local year "2002 2003 2004 2005 2006 2007 2008 2009 2010 2011"
local county "allegany clinton erie franklin madison oneida steuben wyoming
yates"

foreach c in `county' {
	foreach y in `year' {
	capture noisily insheet using "B:/nydata/`c'_`y'_parcel.txt", tab
names clear
	save "`newparcel'", replace
	use "`combinedyr'"
	append using `newparcel'
	save "`combinedyr'", replace
	}

duplicates drop, force
save "`combinedyr'",replace
use "`combinedco'"
append using "`combinedyr'"
save "`combinedco'", replace
drop _all
g testvar=. //to create some data to initially store
save "`combinedyr'", replace
}


use "`combinedco'"
drop testvar
save allparcels.dta, replace
