One notable aspect of the "switch" statement is that of "fall-through", especially as used in the C programming language.
Sometimes it is desirable for a program to loop forever, or until an exceptional condition such as an error arises.
loop is a general loop contruct, not specifically a counting one, although it is often used for that.

 Method of processing an iterative program loop - Patent 4463422
Such program loops are essentially self-contained sequences of instructions in which the last instruction in the sequence repeatedly causes the program to return to the first instruction in the sequence until a terminal condition is reached.
Program loops are an extremely useful programming tool in that they allow an instruction program to guide a computer through highly iterative computations in a relatively economical fashion.
In this instruction program segment, the program loop consists of instructions 42-45 and is designed to perform the subtract, multiply and add operations of instructions 42-44 one thousand times in sequence before the program moves on to instruction 46.

 Ending a program or loop early in C++
On occasion, it may be necessary to end a program (or section of a program) earlier than its normal termination.
The drawback to this strategy is that it ends the entire program (or function) at the point where the return 0; statement is placed.
The test condition is then evaluated as usual, and the loop is executed as long as the test condition remains true.

 Loop Invariants, Correctness, and Program Derivation   (Site not responding. Last check: 2007-11-01)
A loop invariant is a relation among program variables that is true when control enters a loop, remains true each time the program executes the body of the loop, and is still true when control exits the loop.
It is necessary that the loop invariant be true on each iteration before executing the body of the loop, and again after executing the body.

 Method and apparatus for implementing an iterative program loop by comparing the loop decrement with the loop value ...
A method and apparatus for providing program loop control in a data processor employs a special purpose instruction that substantially reduces the program overhead associated with conditional branching at the end of a program loop.
In parallel with decrementing of the loop counter, a conditional branch is executed based on the value of the loop condition code set in the immediately previous iteration of the loop.
whereby conditional branching is performed based on an initialized value of said loop count for a first iteration of said sequence of operations and is performed based on the value of said loop count in an immediately previous iteration of said sequence of operations in a second and subsequent iterations of said sequence of operations.

 ACCEPT vs. LOOP
When the event is received, program execution resumes and the appropriate section of code in the loop responds to the event.
After the code inside the loop is executed, the loop cycles and waits at the ACCEPT statement until another event is received.
While your program is waiting at the ACCEPT statement for an event, the library routines turn control over to Windows so that it can receive events and dispatch them to the appropriate programs.

 PASCAL Programming: Selection and Iteration Structures   (Site not responding. Last check: 2007-11-01)
Computer program design is also facilitated by the use of program structures called loops that cause the block of statements within the loop to repeat or iterate.
A loop limit is a variable or constant that is integer-valued, which determines the number of times a loop will execute, or a maximum value of the loop index to be reached at loop termination.
Here, the loop index is the variable "i", and the loop limits are one and five, with an implicit loop increment of one.

 WXP Program: wxploop
The program offers a window to other WXP programs so that their graphics can be drawn to that window.
Also the program uses the concept of a pixmap which is an allocated portion of memory that emulates a window to create pseudo windows which can be looped or animated.
Once the graphics program exits, the colors are deallocated and those colors displayed on a WXPloop window or pixmap may be changed by the next program that wishes to allocate colors.

 Kenton Lee: Adding External Input Sources to the X Toolkit Event Loop
While the event loop usually requires little code in your program, it actually is the most important run-time component of the X Toolkit.
The event loop is actually one of the busiest part of your program, receiving X protocol events from the X server and distributing them to your program's widgets.
The communication is often intermittent: the source programs usually write to the sockets or pipes whenever they have data and the destination programs then read the data.

 3.12 Iterators and the FOREACH Loop
This is because the program "pushes" the activation record onto the stack upon encountering the FOREACH loop and doesn't "pop" this activation record off the stack until the FOREACH loop fails.
The problem with this code is that the FOREACH loop pushes a whole lot of data onto the stack after the PUSHD instruction pushes the value 10 onto the stack.
Depending on the iterator and the code that calls the iterator, prematurely exiting a FOREACH loop without having the iterator return failure and leaving this junk sitting on the stack may have an adverse effect on the operation of your program.

It's a program that takes two arguments: the code for a program, and its input.

As such, it is a set-based, declarative computer language rather than an imperative language such as C or BASIC which, being programming languages, are designed to solve a much broader set of problems.
Another approach is to allow programming language code to be embedded in and interact with the database.
Like some database-oriented fourth-generation programming languages such as Focus or SAS, SQL assumes a default file structure (data layout), and automates the process of identifying files to the operating system, opening the input file, reading the next record, opening the output file, writing the next record, and closing the files.
