iirc, numbers take up quite a bit of memory. Storing the equivalent string and converting it 'on the fly' with VAL is more efficient storage-wise. -

A small point:
You use LOAD *"m";VAL"d";....
You could just as well do LOAD *"m";d;... which is three bytes shorter. -

Well Paul, it is possible but then you must use VAL$.
This is my reply, I will code an recursive (string)routine later.
