Can't we use the VDP status to guess line number ? Is it not precise enough ?

assembler line number

Hello you all ! In EASy68k, you can use the character "*" as a reference to the current line number. For example, the instruction ds.b $2000-* will reserve a space, padd, from the current line to the $2000 address.

I think it would be 128 x 32, 64 x 64, or 32 x 128.

MOVM.L syntax

Hello. I've stumbled upon the MOVM.L syntax. It's a form of MOVEM that is used by GAS in order to push/pop registers on the stack.
