Using HP Instrument BASIC
Keyboard
or the key combination [Alt]+[F4]. The reason for this is that either the
[Pause] key or the key combination [Alt] + [F4] doesn't work until the
System finishes processing the current program line.
System control keys
[Shift]+[Page Up] Pressing the [Page Up] key while holding down the [Shift] key calls
again the program line last entered (history feature). Pressing the key
combination
[Shift]+[Page Up] repeatedly calls program lines entered
in the past in reverse sequence of entries. Using this feature when you
made mistakes in what you type releases you from typing them over
again. Pressing the key combination
[Shift]+[Page Down] retrieves
program lines in the direction opposite to the case effected by key
combination
[Shift]+[Page Up], and displays program lines.
[Alt]+[F3] Pressing the [F3] key while holding down the [Alt] key executes the
program.
[Alt]+[F2] Pressing the [F2] key while holding down the [Alt] key cancels the
temporary stop of the program.
[F12] With “ALL INSTRUMENT” selected for display layout, pressing the
[F12] key switches the layout to BASIC STATUS mode. Pressing the
[F12] key while holding down the [Shift] key returns the display layout
to “ALL INSTRUMENT”.
Softkeys
The function keys [F1] through [F8] work the same as the softkeys located on the front
panel of the 4294A. The softkey labels are displayed on the right hand part of the screen.
Soft control keys
[F9] This key turns on or off the BASIC menu to control a program and
editor.
[Shift]+[F9] Pressing the [F9] key while holding down the [Shift] key displays the
BASIC menu to control a program. Every time you press this key, the
screen advances to the next page. This menu is the same as the one that
appears when you carry out the key operation
[System] - IBASIC (-
more 1/3 - more 2/3) on the 4294A's front panel.
[F10] This key displays the first page of the BASIC menu to control a
program.
[Shift]+[F10] Pressing the [F10] key while holding down the [Shift] key displays the
ON KEY LABEL menu that displays softkeys defined in the program.
For details, see
“ON KEY LABEL Functions” on page 148.
