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
Famous quotes containing the words jump and/or table:
“Most of the folktales dealing with the Indians are lurid and romantic. The story of the Indian lovers who were refused permission to wed and committed suicide is common to many places. Local residents point out cliffs where Indian maidens leaped to their death until it would seem that the first duty of all Indian girls was to jump off cliffs.”
—For the State of Iowa, U.S. public relief program (1935-1943)
“When I think of our lands I think of the house
And the table that holds a platter of pears,
Vermilion smeared over green, arranged for show.”
—Wallace Stevens (18791955)
