That's a fair point. :-)

Hmmm, no, I don't think so: ARGC and argc have different values, since
argc is what's passed into main by the O/S, whereas ARGC is typically
smaller due to gawk's having consumed some of the arguments.
For example:
bash-4.2$ ./gawk 'BEGIN {for (i = 0; i < length(PROCINFO["argv"]); i++) print
i, PROCINFO["argv"][i]; print ARGC, length(PROCINFO["argv"])}'
0 ./gawk
1 BEGIN {for (i = 0; i < length(PROCINFO["argv"]); i++) print i,
PROCINFO["argv"][i]; print ARGC, length(PROCINFO["argv"])}
1 2
Are you saying it should be '@code{argc} @minus{} 1' instead
of '@code{argc-1}'?

Andy
