loop

View more Technology videos

In programming, a repetition within a program. Whenever a process must be repeated, a loop is set up to handle it. A program has a main loop and a series of minor loops, which are nested within the main loop. Learning how to set up loops is what programming technique is all about.

The following example prints an invoice. The main loop reads the order record and prints the invoice until there are no more orders to read. After printing date and name and addresses, the program prints a variable number of line items. The code that prints the line items is contained in a loop and repeated as many times as required.

Loops are accomplished by various programming structures that have a beginning, body and end. The beginning generally tests the condition that keeps the loop going. The body comprises the repeating statements, and the end is a GOTO that points back to the beginning. In assembly language, the programmer writes the GOTO, as in the following example that counts to 10.

          MOVE     "0" TO COUNTER
   LOOP   ADD      "1" TO COUNTER
          COMPARE  COUNTER TO "10"
          GOTO     LOOP IF UNEQUAL
          STOP

In high-level languages, the GOTO is generated by the interpreter or compiler; for example, the same routine as above using a WHILE loop.

       COUNTER = 0
       DO WHILE COUNTER <> 10
          COUNTER = COUNTER + 1
       ENDDO
       STOP

---

An aerobatic maneuver in which the airplane maneuvers through in a circular path along the lateral axis. It is basically a 360° turn in a vertical plane. If the loop is performed with negative g (i.e., the cockpit remains on the outside of the circle), then it is known as a bunt, or an outside loop. Unless otherwise stated, the term loop refers to a normal loop (i.e., one with positive g and the cockpit remaining inside the circle throughout the maneuver).



Normal loop



Inverted loop



Outside loop



Inverted outside loop
