Programming in HP PPL 553

PRINT Syntax: PRINT(expression or string);

Prints the result of expression or string to the terminal.

The terminal is a program text output viewing mechanism

which is displayed only when PRINT commands are

executed. When visible, you can press

\ or = to view

the text,

Cto erase the text and any other key to hide

the terminal. Pressing

O stops the interaction with the

terminal. PRINT with no argument clears the terminal.

There are also commands for outputting data in the

Graphics section. In particular, the commands TEXTOUT

and TEXTOUT_P can be used for text output.

This example prompts the user to enter a value for the

radius of a circle, and prints the area of the circle on the

terminal.

EXPORT AREACALC()

BEGIN

LOCAL radius;

INPUT(radius,

"Radius of

Circle","r =

","Enter

radius",1);

PRINT("The

area is "

+*radius^2);

END;

Notice the use of the

LOCAL variable for the

radius, and the naming

convention that uses lower case letters for the local

variable. Adhering to such a convention will improve the

readability of your programs.

WAIT Syntax: WAIT(n);

Pauses program execution for n seconds. With no

argument or with n = 0, pauses program execution for one

minute.
