Line 13:

For example:

<source lang=Textawk>

phonebook["Sally Smart"] = "555-9999"

phonebook["John Doe"] = "555-1212"

Line 21:

You can also loop through an associated array as follows:

<source lang=Textawk>

for (name in phonebook) {

print name, " ", phonebook[name]

Line 31:

Multi-dimensional associative arrays can be simulated in standard Awk using concatenation and e.g. SUBSEP:

<source lang=Textawk>

{ # for every input line

multi[$1 SUBSEP $2]++;
