how much bytes of RAM does a sprintf message need?
does anybody have a clue how much bytes this sprintf object: [sprintf append %ld / %ld] would need for each unique symbol?
and in general how to calculate how much bytes a sprintf message is going to need if that's possible?
would i be better of making my own mxj for the task? cpu and RAM wise?
in this case you are not generating more symbols. Append is probably already in the symbol table, and the %ld are numbers. Since you don't use the symout argument it won't output a symbol, so I wouldn't worry about the RAM usage.
