: 23 	Impermissible item after "->"
.br
The assignment arrow must be followed either by a variable,
.br
e.g. "x + y" -> z;"
.br
or by the call up an updater of a function
.br
e.g. "66 -> hd(list);"
.br
If you type "x -> 3" instead of "3 -> x" you'll get an
error, as you cannot assign something to a number. A
number is not a variable.
