<name> - The hashtable where the item resides.
<item> - The hashtable item to decrease.
[num | &binvar] - The number or &binvar to decrease by.

Example

alias countdown {
  ;Adds the item down with a value of 10 to the table count.
  hadd -m count down 10

  echo -a $hget(count,down) $+ !
  :repeat

  ;Checks if the value of down returns true.
  if ($hget(count,down) > 1) {
    ;decreases down by 1
    hdec count down
    ;echos the current count
    echo -a $hget(count,down) $+ !
    ;repeats
    goto repeat
  }
  ;If the previous if statement returns false it carries on with this.
  else echo -a 0, Hurray!
  hfree -s count
}
