perhaps gawk is different, apologies for not taking the time to test, but
in the One True awk, you have to use an extra set of parenthesis:

while ((getline < "FILE") > 0)

I've also found limitations on reading into $0, i.e. in a BEGIN, again from
OTA, so I always read into a variable:

while ((getline x < "FILE") > 0)

writing "portable" awk code has never hurt me
