Branching (GTO)
As we have seen with subroutines, it is often desirable to transfer execution to a
part of the program other than the next line. This is called
branching.
Unconditional branching uses the GTO (
go to) instruction to branch to a program
label. It is not possible to branch to a specific line number during a program.
