Hi
I think that
yes you're right about some BASICs do this jump but not QB (that is the goal of emulation of QB64) and not Dartmouth BASIC (the original BASIC) do this kind of jump with GOTO, so IMHO those are mutant BASICs (GOTO variable) in the family of BASIC (GOTO fixpoint by label or line of number).
