AND IN THIS CORNER ...
Vizastar's first impression is one of
antiseptic, laboratory-like efficiency. The blue
and white ruled display is uncluttered and
inviting.
The spreadsheet is 1,000 rows by 64 columns
in size, controls a 60K workspace and allows
up to 9 simultaneous windows. Though its 30
built-in functions mean business they are
pretty standard, without exceptional entries or
uniqueness.
The most advanced ones include horizontal
and vertical table lookups, ISERR, ISN IF
FALSE, TODAY, DAY and DATE. ISERRR
and ISNA are used to return true (1) or false
(0) values under designated conditions. It's

Revealing its English origins, Vizastar 128
allows users to alter "tone". No, Vizastar is not
talking bells, buzzers and beeps; it's talking
colors. From within the TONE option you can
independently cycle through 16 text or
background colors. This is a welcome feature;
long sessions in front of a CRT are often less
trying when color (colour?) combinations are
changed from time to time.
PIES, BASES AND EXECS
Basic two-dimensional bar charts can be
viewed directly on the worksheet. The pic and
multibar (3-D) graphs display on a hi-res screen
separate and independent from the worksheet.
This enhanced video output is a real eye
popper, particularly the multibar charts.
Where the pie charts arc colorful and
informative, the 3-D images arc vivid, stand-upand-takc-noticc
presentations. Since they both

use the same colors and are displayed at the
same resolution, you may ask "What's the
difference?" It's a matter of depth and shading.
The pics are two dimensional (no flavors
cither) while the multibars have a contrasting
shadow which serves to accent and strengthen
the image.
Both types show little or no color bleed.
While build times (the time it takes for the
chart to draw on-screen) are not instantaneous,
they aren't excessive either. Both types are
worth the wait.
The database is rather full featured. Its
generous limits allow up to 9 screens per
record, 8,000 characters per record and up to
16 separate files per disk. The number of
records and databases is limited only by disk
space.
