**Computer Monthly, October 1991: ***"Were
IHA the product of ... Microsoft, ... 'revolutionary' and 'novel'
would have become a regular part of the industry press cliches
about it." *

**OS/2 & Windows Magazine, October
1991: ***"... I thought, 'This would be nice for my kids
to learn math with. ... I certainly didn't expect to recreate
some of my more extravagant Lotus, Wingz or Excel spreadsheets
..." *

**THEIRS: Every cell gets a name
defined by a column letter and row number. A calculated cell is
described by the algebraic formula you lodge in it. That formula
may draw input values by using cell names. Ordinary algebraic
conventions like the use of parentheses govern the sequence of a
calculation. When not working on the formula, it disappears and
is replaced by the resulting value. **

**OURS: No cell names. No formulas
using cell names. How? Think about a hand calculator. You input a
value, an operator, another value, etc. IHA's approach is
similar. You place operators next to the values. Use the mouse or
type them in. Accidentally naming the wrong cell in a
calculation, a chronic problem for the conventional spreadsheet,
disappears. **

**Both theirs and ours have honed
strategies for replicating calculations, making use of complex
functions, and generating graphs. IHA is innovative and
practical. Its original look and feel removes the drudgery from
specifying calculations and provides a visual perspective that
prevents mistakes. **

**Above is a sample equation to
calculate the total of expenses. The two blackened boxes show
that the equation is to be used twice starting once at the
location of the first black square and the second time starting
at the location of the second black square. With IHA, making a
spreadsheet feels like painting a picture or working at a
blackboard. The numbers next to the operators show the order in
which each is used. IHA tracks the order in which operators are
used as you click them into the picture. **

**While all this may look like the
first time you were exposed to arithmetic in elementary school,
IHA is not a toy. **

**IHA can handle a variety of
applications not traditionally associated with a spreadsheet.
Here are a few features you may not have expected: Sorting.
Calculations with dates and times. Logical comparisons for
numeric and character data. Searching and replacing. Mortgage
calculations and other built-in functions. Iterations and goal
seeking. You can even make charts from the numbers in your
spreadsheet. **

**You can download a ZIP file that
installs IHA, the Touchpoint Viewer, 30 examples, and an
electronic manual using the Viewer. It's all bound up in one 415K
file. Simply run INST_IHA.EXE after unzipping the download.
You're not only going to be impressed with IHA, but with the
Viewer as well. **

**If you decide to become a licensed
user, send a check for $9.95. To obtain the complete wire bound
manual as well, send a check for $23.90. Shipping and tax (for
California residents) is included. You'll find these terms and
our address in the package downloaded. It's simple. It's easy.
