Assign value to external variables from awk
Hello
I have a text file with the next pattern
Code:
Name,Year,Grade1,Grade2,Grade3
Name,Year,Grade1,Grade2,Grade3
Name,Year,Grade1,Grade2,Grade3

I want to assign to external variables the grades using the awk method.
After i read the file line by line in order to get the grades i use this
Code:
grade1=echo $line | awk -F, '{ print $3 }'
grade2=echo $line | awk -F, '{ print $4 }'
grade3=echo $line | awk -F, '{ print $5 }'

Is there a way to assign values returned by awk to external variables from inside the awk command?
I know the next code wont work but something like this
Code:
echo $line | awk -F, '{ grade1= $3; grade2= $4; grade3= $5; }'

Thanks

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).

       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
