Programming 594
Because a Goto command is unconditional (it always branches to the specified label), it
is often used with an
If 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.
