HP-UX Technical BASIC

runs

in

a multi-tasking

environment

on

the

Intergral PC. This

means

that

users can

have

several

processes

running

at

the

same

time. For example, you

may

start a

program

in

the

BASIC

window

and

then

return

to

the

PAM

window. From the

PAM

window

you can

start

other

programs

while

your BASIC

program

is running. Multiple

windows

are also useful

when

you

need

to

run

a

system

util-

ity

while

you are

in

BASIC.

To

format

a disc, for example,

simply

return

to PAM

and

run

the

format_disc utility,

then

return

to BASIC

and

continue.

Both

the

BASIC interpreter

and

your BASIC programs

run

in

the

BASIC alpha window.

If

the

BASIC

program

uses graphic

statements

the

BASIC interpreter will create a BASIC graphics

window.

HP-UX Technical BASIC contains approximately

47

BASIC

keywords

used

to control

the

graphics

window

or

plot. This

section will discuss some

of

the

machine

specific aspects

of

graphics. For more

information

on

how

to

program

using

the

graphics statements, refer to HP-UX Technical

BASIC

Program-

ming Guide.

To

enable

you to use

the

BASIC graphics statements,

the

BA-

SIC interpreter will automatically load

the

HP-GL

(Hewlett-

Packard

Graphics Language) driver contained

on

the

BASIC

disc. And, unless

the

plotting

device

has

been

reassigned,

it

will also automatically create a BASIC graphics

window

when

the

first graphics

statement

is executed.
