I don't think so, although I have to admit Man pages are not the easiest thing to understand.
I think this for the following three reasons:
1) I don't use the parameter until after the BEGIN statement
2) This wouldn't quite account for the different results I get from the same script just run on an SGI and SUN.
3) I can do math on the parameter (sorry I lied). What I can't do is use the parameter in an elvaluation test (i.e. an if test). If I use it in an if statment it just seems to set the parameter to zero. Yet if I print the parameter in the then part of the if statment it gives me it's correct verion.
I have look around for alternate version of AWK but don't have the one you mention but I do have nawk, oawk & pawk.
My main curiosity was why it awk would fail like that. I can get roung the problem by confining the awk scripts use to SGI machines.

IGAWK(1) Utility Commands IGAWK(1)
NAME
igawk - gawk with include files
SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ...
igawk [ all gawk options ] [ -- ] program-text file ...
DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).
AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like
@include getopt.awk
in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.
OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports.
EXAMPLES
cat << EOF > test.awk
@include getopt.awk
BEGIN {
while (getopt(ARGC, ARGV, "am:q") != -1)
...
}
EOF
igawk -f test.awk
