What jmp instruction assembles if distance is 0020h bytes?

If the distance for a JMP instruction is 0020h bytes, it typically assembles to a short jump instruction (if the target is within a certain range) or a near jump instruction. In this case, a near jump would be used, which consists of the opcode followed by a 16-bit offset. The exact opcode will depend on the assembly language and architecture, but for x86, a near JMP could be represented as EB for a short jump or E9 followed by the relative address for a long jump.
