You should also note that the value of SUBSEP varies in different implementations of awk (and I don't remember what value nawk uses). Some systems (for example OS X) default SUBSEP to an empty string.
Any implementor who chooses an empty string for the value of SUBSEP should be shunned by the AWK community . Seriously, though, the chance for collisions would be too great.
OS X's awk is nawk (which is also used by the BSD systems). "\034" is also the value of SUBSEP in the mawk, GNU awk, and busybox awk implementations.
In light of this, fiddling with SUBSEP is usually unnecessary.

Hello,
I'm writing an Awk script to take a command line argument (student's name) and output their relevant student#, name, and marks. For some reason, awk arbitrarily removes the first digit from the student number and doesn't show me the proper output.

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
