i had completely misunderstood the 'array' as a TYPE rather than a NAME :-(

with your changes (above), works perfectly.  cool!

also, from your prior post:

define([MY_IP_ADDR2],
esyscmd([dig @]MY_DNS_NAME MY_HOST_ARRAY(2)[ | awk 'index($ 0, 
"]MY_HOST_ARRAY(2)[") == 1 {printf("%s", $ 5) }']))

works perfectly, now, as well.

next, to figure out multi-dimensional arrays ... but 1st, i need to get some 
sleep.

thx! =)
