CPU & Memory AWK: How to avoid System

How can we avoid the use of system command inside awk program?
Is there any alternative way in awk programming for removing files, sorting files and to find the differences between two file without using a system command?
Eg:
system("rm tempfil006");

How to avoid the use of system in above case and other similar cases inside awk program as the use of system is slowing the program execution??

Please help

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 SEE ALSO
