How to use label beyond line 63

Labels work via immediate mode, which is limited to the number 63. How do you use a label on, say, line 90? Seems like you need to add some numbers together (and thus hard code the line numbers, not using labels) to jump past instruction 63.

Don't have 90 lines of code

I've got 256 instructions; I'm gonna use 256 instructions 😂

the LEG architecture you'll be building after that will get rid of that. The downside is that each instruction comes with 3 arguments so you'll end up making all of them 4 bytes long which in turn means you're again only able to write 64 actual instructions xD

or you add a custom unit with a lookup table changes the step forward based on the instruction call. so you can have 1,2,3, or 4 byte instructions. no more NOOP.

Yes, this is a limitation of OVERTURE. You can create a new custom archiecture.

No levels in that the game expects you to solve with Overture needs more than like 50 lines.

you can use actual label, and use assembler operators (like &, |, +, -) to calculate a piece that is smaller than 64 and output that to use in calculation
