-Then:
+First, it can dump regular variables:
 <code>
-$ dump PATH HOME
+$ dump HOME HISTFILE HISTSIZE
-PATH = /home/rpjday/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/usr/local/go/bin:/home/rpjday/bin:/home/rpjday/go1.11.4/go/bin
 HOME = /home/rpjday
+HISTFILE = /home/rpjday/.bash_history
+HISTSIZE = 1000
+$
+</code>
+Next, dumping regular arrays:
+<code>
+$ people=(fred barney wilma betty)
+$ dump people
+people = fred barney wilma betty
+$
 </code>
-And arrays:
+Finally, dump a bash associative array:
 <code>
-$ ARR=(fred barney wilma betty)
+$ declare -A wife
-$ dump ARR
+$ wife[fred]=wilma
-ARR = fred barney wilma betty
+$ wife[barney]=betty
+$ dump wife
+wife[fred] = wilma
+wife[barney] = betty
 $
 </code>
