Using Forms in Programs

Once you have completed the design of a form and have saved it to disk, you are ready to incorporate it in a PL/B program.

To include the form in a program:

1. Define the form using the PLFORM declaration.

2. At the point in your program where you want the form to be displayed and become active, use the FORMLOAD instruction.

 

A basic program to display a form is:

 

MAIN      PLFORM      MYFORM.PLF

.

           FORMLOAD      MAIN

.

           LOOP

           EVENTWAIT

           REPEAT

 

Simply substitute your form's disk file name for "MYFORM.PLF" and it is ready to compile and run.
