Thank you as always for the great help and explanations

---------- Post updated at 07:30 AM ---------- Previous update was at 07:00 AM ----------
I am still a bit confused on this concept:
Quote:
#### Putting the values of subtring whose value starts from RSTART+1 to RLENGTH-2, here point to be noted RSTART and RLENGTH are the OOTB awk's keywords which will be SET when a match is found, we have done this match for 5th field above
I guess my confusion is what defines RSTART+1 and RLENGTH-2 in this line but RSTART+20 and RLENGH-22 in the print?
In the first RSTART
$5 was used as the substring, so
chr15:88483984, so is
RSTART+1 the
chr15 and
RLENGTH-2 = to
:88483984? Thank you

IGAWK(1) Utility Commands IGAWK(1)
NAME
igawk - gawk with include files
SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ...

DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

@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
