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:
“Well, you look so pretty in it
Honey, can I jump on it sometime?
Yes, I just wanna see
If it’s really that expensive kind
You know it balances on your head
Just like a mattress balances
On a bottle of wine
Your brand new leopard-skin pill-box hat.”
—Bob Dylan [Robert Allen Zimmerman] (b. 1941)
“A man who can dominate a London dinner table can dominate the world. The future belongs to the dandy. It is the exquisites who are going to rule.”
—Oscar Wilde (1854–1900)
