I have attached a simple patch below in txt format. I dont understand why when using the 'symbol' object I can instantiate the $1 variable to a string and when I try the same with the $2 variable it says "error: $2: argument number out of range".

Just to comment on that specific problem as well: By sending a message [word( to a [symbol] object's first inlet, that message also will be converted to a proper symbol message: "symbol word". Now if you send this to a message [$1(, it will correctly print "word". But if you send this to a message [$2( as in your patch, Pd complains, because the message "symbol word" doesn't have a second data item to access with $2.

Also you seem to misunderstand the difference between $-variables in messages and in object boxes. In object boxes, $1 will be replaced by the first argument of the parent patch, that is, the patch that includes an object having the same name as the patch, that contains the [symbol $1] (the abstraction).

However if open such an abstraction directly without calling it through a parent patch, $1 and all subsequent $-variables in object boxes will be initialised as 0.

Anyway sending a message into a [symbol $1] object will overwrite that initial argument with the incoming word.
