Repeating the "Transaction Handling Task"

A task can be big. It may take many statements to complete it. What a "task" is depends on how much detail you are considering at the moment. The current version of the program can be considered to be made up of two tasks:

• Get the starting balance.
• Handle one transaction.

The "handle one transaction" task is made up of smaller tasks, but right now think of it as doing one activity -- dealing with one transaction.

To repeatedly perform a task use a DO WHILE...LOOP structure. Here is the control structure for the new version of the program:

_____________

'
DO WHILE user does not want to quit

  _____________
  
  ask if user wants to quit
LOOP
'
END
