Hello,
I'd like to ask if the number of variables in expressions could be
increased from 10 to 25 please. I mean the st() and ld() functions. I'm
just programming a realtime wormhole simulation and the limitation to 10
variables is becoming nasty. I did already begin to re-use the same
variables for different things, but that makes debugging complicated. It
would be so much easier to have more variables and use each one only for
one thing.
What you see below is only a small part of the code.
Thanks,
Michael
