HIGH-LEVEL

LANGUAGE

FOR

6140

To further

support

the 6140 Development System,

~IDL/u,

Modular Development Language for Micros,

now

available on the

8560 for 8-bit microprocessors, 8080, 8085,

and

Z80/NSC800.

MDL/u,

based on the BASIC

language, has been expanded specifically to

support

microprocessor-based

product

development.

The

extensions include:

" • Direct access

I/O

ports and addresses

•

Interrupt

handling

• Modularity

Features

- Separate compilation of modules and combination with assembly language modules

• Procedure definition

execute an algorithm as well as function definition to

return

a value

• Extensive

support

for manipulation

strings

• Logical operations on integers as well as shift and

rotate

operations for

bit

manipulation

• Descriptive variable names

We are offering two products on the

8560/61 development systems: MDL8085 for 8080/8085

and

MDLZ80 for

Z80/NSC800.

Included with the

~'IDL/u

product

a Class C program, Rational, which provides program execution constructs

for MDL/u.

runs as a preprocessor to

the

MDL/u

compiler.

See

the following article, RATIONAL PROGRAM-

DEVELOPMENT

LANGUAGE

FOR

THE

8560(1)

Tektronix

announcing the availability of the

Rational

preprocessor for the

Modular

Development

Language

compiler

(MDL/u).

The

preprocessor

and

the compiler are available for the 8560

and

8561 develop-

ment

systems.

The

source for

the

libraries will

provided

allow the user

tailor the language implementa-

tion

the needs of the design. \Vhile floating point capability

not provided, extensive

support

is provided for:

•

the manipulation of strings (up

255 characters long) including string arrays,

• 8

bit

and

bit

integers and integer arrays including boolean operations,

•

interrupt

handling,

• and direct access

I/O

and memory.

Separation of code, constants, and variables provides prototype configuration capability. Code generated may be

easily combined with code generated from assembly source.

Since the control constructs of

MDL/u

are somewhat limited,

have developed a preprocessor called

Rational.

Rational

provides complete

set

of execution control constructs as well as

other

enhancements

that

will be

described later.

Rational

produces

MDL/u

source which subsequently can be used with the 8080, 8085, Z80,

and future versions of

MDL/u.
