Chapter 7, IBASIC Controller
The IBASIC Controller Screen
The TESTS (IBASIC Controller) screen can be accessed programmatically by sending the
following command:
OUTPUT 714;"DISP TIBasic"
The TESTS (IBASIC Controller) screen is divided into several areas which are
used by the IBASIC controller for different purposes.
The small horizontal rectangle at the top left is the IBASIC command line. As the
name implies IBASIC commands can be executed from this line. Commands can
be entered locally using the rotary knob or remotely using serial port 9. A
maximum of 100 characters may be entered into the command line.
The vertical rectangle at the top right side is the softkey label area. The five
highlighted areas within the softkey label area correspond to the five special
function keys on the front panel of the Test Set. IBASIC programs can assign
tables to these keys and control program execution by using ON KEY interrupts.
The vertical rectangle at the bottom right side is the
To Screen
area and is the
same as the
To Screen
area displayed on any other Test Set screen. The user
may switch to some other Test Set screen by using the rotary knob to position the
cursor onto the desired screen and then pushing the knob.
The large rectangle in the center of the screen is the CRT (display screen) for the
IBASIC controller. The IBASIC controller uses this area for, displaying alpha,
numeric, and graphic information, program editing, program listing and so forth.
This area operates as would the CRT on an external Hewlett-Packard 9000 Series
200/300 Workstation.
