Example: #variable alignlist {1 2 3}
#getl Length {$alignlist} <--- returns 3 in the Length variable
Another Example:
#delimiter {;;}
#var list {n;e;s;;get all;n;;e;e;s}
#getl Length $list
The delimiter ";;" breaks the $list into: {n;e;s}, {get all;n} and {e;e;s}
three parts, thus Length variable is now 3.
