Loop, exiting from

In Program QWIEN (written in QBASIC, Appendix A), x is initialized at 1 and incremented by 0.1 in line 3, which is given the statement number 10 for future reference. Be careful to differentiate between a statement number like 10 x = x -E. 1 and the product 10 times r which is 10%. A number a is calculated for x= 1.1 that is obviously too small so (a — 1) is less than 0 and the IF statement in line 5 sends conhol back to the statement numbered 10, which increments a by 0.1 again. This continues until (a — 1) > 0, whereupon control exits from the loop and prints the result for a and a . 

If a molecule is strained, atoms may not be ver y close to the minimum of their individual potential energy wells when the best compromise geometry is reached. In such a case, the geometric criterion does not provide an exit from the loop. Programs are usually written so that they can automatically switch from a geometric minimization criterion to an energy minimization procedure. 

Often you use a loop structure to search through an array or collection of objects, looking for a certain value or property. Once you find a match, you don t need to cycle through the rest of the loops. You can exit from the loop using the Exit For (from a For...Next loop or For Each...Next loop) or Exit Do (from a Do While... loop). The Exit statement will normally be located within an If statement. For example.

Standard BASIC includes several loop constructs. The general loop eonstruct can have the exit condition attached to the DO statement, attached to the LOOP statement, or loeated somewhere in between. The following program fragment illustrates the middle exit from a DO loop ... 

Alternative ways of coding that fragment without using the EXIT DO statement are either longer or more obscure. Standard BASIC also allows exiting from the middle of a FOR-NEXT loop. Standard BASIC includes a variety of constructs for making choices for example ... 

In this equation now, Tq will be the residual tension existing at the entrance to or the exit from the knot where the suture ends are positively gripped by the compressive forces, n will be equivalent to the number of throws, is the twist angle, and ji is the coefficient of friction. The tension T can be obtained directly from the measurements of the KHF by the loop method and can be equated by empirical means to suture size, tensile and frictional properties, and parameters of knot construction. The value of T, the actual tension existing along the inner loop ends and exerted by the tissues, however, remains to be determined but can be expected to depend upon, among other factors, the size of the suture loop, the tension used to tie the knot and the mechanical and visco-elastic properties of tissues approximated. 

Type 103 is formed with one thread and a curved needle that passes from the left to the right, entering and exiting from the same side of the material carrying a needle thread that is intercepted by a bhnd looper (Figure 10.6). It can be used for hemming, belt loops, and felling operations. 

The exit from the iterative fitting loop is made automatic or manual when x is less than 10 . For those elements which are not detected, the program can also provide the limit of detection (ppm) calculated as 2>y/B/S, where B is the integrated background (i.e., nonpeak) count in a region centered at the computed centroid and having a width of one FWHM while S is the number of counts of elemental X-rays in the line. 

WHILE loop and FOR loop are transformed into UNTIL loop so that the exit from the loop can be always in the last c-step for the loop, as shown in figure 8. The CVLS scheduling exploits concurrency between the loop conditionals and loop body operations, which could shorten the execution c-step of the loop. 

Loop unrolling—transforming a loop into a linear sequence by making copies of the loop body—illustrates how automata-theoretic algorithms implement structural transformations. Consider a machine which executes a definite loq) (one whose iteration bounds are known at compile time) such a machine can be built from a sequencer and a counter as shown in Figure 7. The sequencer resets the counter at the start of the loop, increments it at the end of each iteration, and exits the loop when the counter reaches its limit. The loop body performs a simple assignment The state transition table for the sequencer component is shown in Figure 8 we have used more states than necessary in the sequencer to more clearly illustrate how the loop unrolls. 

For Loops are usually supported by synthesizers, the While and Infinite Loops may not be supported. Always provide a means of exit from a loop. 

HardwareC supports a single-in, single-out control flow. This implies that no gotos, breaks from loops, and returns from procedures (other than at the very end) are allowed. It supports the usual iterative and branching control-flow constructs. Iteration can be specified eitha as fixed-bound loops (for loop) or data-dependent loops (while or repeat-until loops), depending on whether the loop exit condition is known at compile time.
