However, the only form of a branching instruction available was a hard-coded unconditional branch (GOTO) that always executed at program completion (the end of the operation stack) to return to the starting instruction of the program (looped back to the beginning of operation stack).
However, the only branching mechanism available was a hard-coded unconditional jump (GOTO), which always executed at the end of the program's execution (the completion of the operation stack) and then returned to the initial instruction of the program (looping back to the beginning of the operation stack). A single GOTO could target numerous instructions.
