awk uses associative arrays, before you ask.
Hello,

I used the code you provided as follows. In my shell script I have a line that calls the awk script:

awk -f processing.awk names.tmp

In processing.awk I modified your code as follows:
{ arr[$1]++; continue }
END { for (i in arr) {print i, arr[i] }

When the script runs it says:
awk: processing.awk:3: { arr[$1]++; continue }
END { for (i in arr) {print i, arr[i] }

awk: processing.awk:3: ^ syntax error

Can you help me troubleshoot the problem please?

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
