Programming

 610

Because a 

 command is unconditional (it always branches to the specified label), it 

is often used with an 

 command so that you can specify a conditional test. For example:

Ê

 If x>5, branches directly to label GT5. 

Ë 

For this example, the program must include commands (such as Stop) that prevent Lbl GT5 

from being executed if x

{

5.

Using Loops to Repeat a Group of Commands

To repeat the same group of commands successively, use a loop. Several types of loops 
are available. Each type gives you a different way to exit the loop, based on a conditional 
test.
