Chapter 6, IBASIC Controller
Method #2. Developing Programs on the Test Set Using the IBASIC EDIT Mode
Method #2. Developing Programs on the Test Set Using the IBASIC EDIT
Mode
If a BASIC language computer is not available, program development can be
done directly on the Test Set using the IBASIC EDIT mode. A terminal or PC
connected to the Test Set through RS-232 is used as the CRT and keyboard for the
Test Set’s built-in IBASIC controller. In this method, the program always resides
in the Test Set and can be run at any time. Mass storage is usually an SRAM
memory card. When running IBASIC programs on the Test Set’s internal
controller, the Test Set displays only the IBASIC screen.
The Test Set’s IBASIC controller has an editor that is interactive with a terminal
or PC over the RS-232 serial port. (The editor does not work unless a terminal or
PC with terminal emulator is connected to Serial Port 9.) The editor, hereafter
referred to as the “IBASIC EDIT Mode”, allows the programmer to develop code
directly in the Test Set with no uploading or downloading. The IBASIC EDIT
Mode can be used to develop programs from scratch or to modify existing
programs. Refer to
"Interfacing to the IBASIC Controller using Serial Ports" on
page 246
for information on connecting a terminal or PC to the Test Set.
Selecting the IBASIC Command Line Field
To use the IBASIC EDIT Mode for program development, the IBASIC Command
Line
field must be displayed on the Test Set and Serial Port 9 must be connected
to the
IBASIC Command Line field. An IBASIC command, sent as a series of
ASCII characters through Serial Port 9, will appear on the
IBASIC Command
Line
field. When a carriage return/line feed is encountered, the Test Set will
attempt to execute the command. To display the
IBASIC Command Line field
on the Test Set execute the following steps:
1. Press the TESTS key.
2. The TESTS (Main Menu) screen will be displayed.
3. Using the rotary knob, position the cursor on the IBASIC Cntrl field and select it.
4. The TESTS (IBASIC CONTROLLER) screen will be displayed.
5. The small horizontal rectangle at the top-left is the IBASIC Command Line
