A New Backspace

Under HP BASIC, the BACKSPACE key was assigned to

CHR$(255)&”B”. This function does the same thing that

the LEFT arrow key does. HP BASIC is unique in this

treatment of the BACKSPACE key. For compatibility with

the remainder of the computing community, HP BASIC

for Windows assigns a new function to the BACKSPACE

key. Pushing BACKSPACE deletes the character to the

left of the cursor. This function is named DEL LEFT and

is equivalent to the function LEFT followed by DEL CHR.

If you do not like this definition, you may be able to

redefine the key using the CONFIGURE KEY statement.

Series 300 Bit-Mapped (CRTB) Displays

If using an HP 9816, 9836, or other HP computer with

separate alpha and graphics hardware, some of the

differences you find in HP BASIC for Windows will be

the same differences you would find moving to an HP 310

or another HP computer with a fully bit-mapped

alpha/graphics display. On bit-mapped displays, the

ALPHA image is written into one or more of the graphic

planes. On HP BASIC/9000 workstations, one plane can

be separated from the others for use solely for the

ALPHA image. Or, all the planes can be merged for

shared use between ALPHA and GRAPHICS. HP BASIC

for Windows supports both separated and merged mode.

When ALPHA and GRAPHICS are merged, ALPHA text is

converted to graphic bits and written into the graphic

planes, overwriting any graphics data that might be

present. Therefore, ALPHA and GRAPHICS cannot be

dumped separately. And when the ALPHA text is scrolled,

any graphic data present will be scrolled also.

CRTB Mode is the default for Windows system drivers.

This mode gives the best HP 9000 emulation.

9836C (CRTA) Displays

The HP 9836C display is driven by CRTA Mode drivers.

A CRTA display has distinct ALPHA and GRAPHICS

images. Either the ALPHA or GRAPHICS images can be

displayed, or both can be displayed at once, overlapping

each other. The hardware for the two images is

independent. HP BASIC for Windows emulates CRTA

Mode drivers.

Porting HP BASIC/9000 Programs

to HP BASIC for Windows Version 7.0

and Above

One of the hallmarks of the HP BASIC family has been the

ability to develop applications which will run on a variety

of computer platforms. HP BASIC for Windows adds the

PC platform to the RMB

(Rocky Mountain Basic

) family.

This product note describes differences between

HP BASIC/9000 (Including Series 200, 300, 400, and 700

computers) and HP BASIC for Windows. Differences in

hardware, file system, and keywords are discussed to help

you move programs to HP BASIC for Windows from other

HP BASIC platforms.

The CONFIGURE command allows you to customize

HP BASIC for Windows to more nearly match the

configuration of an HP 9000 computer. This command is

described completely in the documentation supplied with

the product.

Hardware Differences

HP BASIC for Windows compensates automatically for

many of the hardware differences that exist between

an HP BASIC/9000 and other hardware platforms.

The following sections outline many of the differences

and explain what limitations still apply.

Disk Drives

GPIB disk drives are not supported. No mass storage

device is supported across the GPIB. HP LIF disks are not

compatible with DOS disk formats and cannot be read or

written directly by HP BASIC for Windows. However,

there are LIF utilities provided with HP BASIC for

Windows for transferring files from LIF disks. These

utilities work with most PC floppy drive mechanisms.

Softkey Layout

Different keyboard layouts are used by HP BASIC/9000

and PCs. Some PC keyboards have the softkeys down the

left side of the keyboard, and some have them across the

top of the keyboard. To make up for these differences and

the lack of spatial coherence between the physical keys

and the softkey menu, HP BASIC for Windows menu

labels have been numbered to provide numerical

coherence. The label numbered “1” always corresponds to

the softkey with the 1 printed on it. The number is not

meant to be the softkey number.

To provide compatibility with programs written for the

9836 Nimitz keyboard (which starts with softkey K0), the

command KBD CMODE can be used to turn on or off

compatibility mode.
