It's "okayish". To store the symbol, I use a data-structure array of number/symbol
pairs, where the number is used as a flag if a symbol is active or "deleted".
So your symbolarray can have "holes", but OTOH if you create an array with only
one symbol stored at position 20,000 it will use up the memory of 20,000
symbol/number pairs. But so does a [table] ...
