Print smallest integer from file using awk custom function?

`awk` function looks like this in a file name `fun.awk`:
Code:
    {
    print small()
    }
    function small()
    
    {
    a[NR]=$0
    
    smal=0
    
    for(i=1;i<=3;i++)
    {
    if( a[i]<a[i+1])
    
    smal=a[i]
    
    else
    
    smal=a[i+1]
   
    }
    return smal
    }

The contents of `awk.write`:

Quote:

The `awk` command is:

awk -f fun.awk awk.write

It gives me no result? Why?

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
