[SR-Users] why is while loop not terminated?

i'm in the process of enhancing enum mudule enum_query, so that suffic param can be given in a pseudo variable. before committing to git, i tested if the new version is working correctly, and for that purpose wrote this kind of route: route [PERFORM_ENUM_QUERIES] { xlog("L_INFO", "suffix_list = <$var(suffix_list)>\n"); $var(i) = 0; $var(domain) = $(var(domain_list){s.select,0,,}); while ($var(domain) != "") { xlog("L_INFO", "Query $var(i) for $var(domain)\n"); if (enum_query("$var(domain)")) { xlog("L_INFO", "Return success!\n"); return(1); }; $var(i) = $var(i) + 1; $var(domain) = $(var(domain_list){s.select,$var(i),,}); }; return(-1); } looks like the enhanced enum_query works as expected, but the while loop is not terminating by the return(1) statement (see below). i'm puzzled. have i done some stupid mistake that i cannot see? -- juha Mar 24 18:29:56 localhost /usr/sbin/sip-proxy[24589]: INFO: suffix_list = <e164.test.fi.> Mar 24 18:29:56 localhost /usr/sbin/sip-proxy[24589]: INFO: Query 0 for e164.test.fi.
