the old by simply changing the
first
byte of the file header to a new, unused
value.
As for a data dictionary, it could be
partially included as an expanded file
header with a section for field descrip-
tions. However, the most intuitive and
compatible way to create a data dic-
tionary would be to create a system
variable for FoxPro that, if true, would
require the entry of related data into a
dictionary file during Create and
Modhy Structure operations. While the
data dictionary variable is true (Datadic
=
.T.) creation of .dbf files via the Copy
command for data and structures
would also copy the data dictionary
files when related dictionary files exist.
If the system variable is set to
false
the
data dictionary entries would not be
required and thus the ability to do quick
and simple tasks would be retained.
These dictionary files could be named
.dtd (DaTa Dictionary) files.
The three most used types of
software on micro computers are
wordprocessing, spreadsheets and
database management systems. Isug-
gestthata
very
important future path for
DBMS development is the inclusion of
wordprocessing and spreadsheet
functions. FoxPro is well on its way
toward the first mentioned function with
its internal editor but really needs a way
for the developer to capture and con-
trol keystrokes. Something similar to
the way that Clipper allows this in
its
MemoeditO function via a UDF is often
mentioned by other developers I
speak
with as a desirable feature for FoxPro.
If you consider one of the principal
aspects of spreadsheets the manipula-
tion of rows and columns of data while
it is retained in memory then the
second function of spreadsheets is not
as well addressed in the current ver-
sion of FoxPro. Neil Weicher publishes
a useful library (d123 from Com-
munications Horizons) that reads and
writes Lotus 123 .wks files and
provides some functionality and 123
command emulation. Similar
functionality in FoxPro would meet
some of the needs I see in the cor-
porate world where users take informa-
tion from databases into spreadsheets
and sometimes back into the
databases.
When these issues have been ad-
dressed and resolved the Dbase lan-
guage developers will be able to com-
pete in the database applications
world not only with the traditional
Dbase strengths of lower development
times and greater simplicity but also
meet the corporate challenges of con-
nectivity, greater
functionality and
commonality of
user interface.

Chuck cranked right Out of the Fox. He
also showed us avery interesting database
benchmarking program he has developed
in conjunction with other Macintosh con-
sultants, to test Foxbase/Mac’s perfor-
mance against other Macintosh database
programs and (he hopes!) against FoxPro
as well.

Winston Churchill was reviewing
the corrections made by a staff assis-
tant to the draft of a speech he had
written. The Prime Minister found a
particular sentence, which he con-
sidered perfectly fine, red-lined be-
cause it ended with a preposition. He
lost his patience and furiously penciled
his retort:
"This is the sort of errant pedantry
upwith which I will not put!” he wrote.
