The shells can parse fields if you change to $IFS to include the right field separators, preferable in a subshell so life is not severly bent for the rest of the shell. In place if ths space and tab separators in $IFS, put your simple delimiters, and then they are separated in terms of 'read', 'for myvar in' or arguments on a command line or shell function call. It's pretty simple, really. Something like "while read f1 f2 f3 f4 f5 f6 f7 f8;do . . . done" suggests itself. You can also subdivide fields in shell using ${varname%} or %%, #, ##. Substrings are a bit more work in ksh, but bash has this more gracefully built in:

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
