FORCE

The main feature was a presen-

tation on the FORCE compiler

from Sophco (the evening after

the a similar presentation at

DLaP). David Lowery, one of

the principals at Sophco showed

what a knowledgeable program

developer can do with FORCE.

FORCE is a different breed

from Clipper in that it produces

true native code and can thus

create a very small fast .EXE file.

Clipper .EXE files actually

contain a runtime interpreter -

the actual program is compiled

to a token table that is subse-

quently executed by the runtime

interpreter.

FORCE does require that all

variables be declared and typed

prior to use just like the other

major compilers on the market

such as C. Syntax checking is

done as a part of the compile

cycle instead of in the runtime

cycle as with other Dbase lan-

guage compilers. FORCE uses

Microsoft C calling conventions

so C segments and assembler

segments need no special pa-

rameter passing schemes.

FORCE has outstanding support

for arrays, conditional compila-

tion, include files, defines and

@..prompt..message menuing.

The October Meeting

Come hear Ashton-Tate on

dBASE IV Version 1.1 (the one

that works). Gain the feedback

from the recent developers

conference. What you see and

hear may amaze you (another

compiler???). If you must miss

the DLaP presentation, you are

welcome to join us at the Valley

Clipper Group.

L.A. Fox

Dahlin, George Dvorak, and

myself led off with short pre-

pared topics to get things started.

It worked. The group picked up

the threads and launched into

some lively discussions which

were quite informative — I

learned several useful things I

didn’t even know I wanted to

know. We will try this format

again in future meetings, so

anyone who would like a forum

for discussing a database design

problem or asking for help with a

development technique, please

let me know.

You don’t have to prepare slides

or overheads for this kind of

session, and there can be PC

and/or Mac equipment available

for hands-on work if you let us

know in advance. The group is

small enough and congenial

enough to make this effective.

Board of Directors

We have a new member of the

LA Fox Board of Directors.

Warren Rekow joined the board

at our last meeting. Warren

works at Hughes, has been a

regular at our general meetings,

and will start helping with our

membership database.

October Meeting

Our October meeting features a

very successful local consultant,

Jay Rubin. Jay is Vice President

of DFC Enterprises in Newport

Beach and has been closely

involved with Dbase related

products since their beginnings.

His clients range from small

businesses to large Fortune 500

corporate giants.

Of interest to this group, he

works with Fox software in both
