Jump Table Example in PL/I
PL/I implements a jump table as an array of label variables. These may be initialized in an unusual way by using a subscripted statement label. PL/I label variables are not simply the address of the statement, but usually contain additional information on the state of the code block to which they belong.
declare lab (10) label; declare x fixed binary; goto lab(x); lab(1): /* code for choice 1 */ ; ... lab(2): /* code for choice 2 */ ; ...Read more about this topic: Branch Table

To the built voice, or fly with winter to the bells,
But do not travel down dumb wind like prodigals.”
