“MacElements Utilities” is a HyperCard 2.x stack which calculates element percentages and isotope patterns for given chemical formulae together with yields of chemical reactions. It should therefore be useful in any chemical laboratory.
All the user has to do is enter the formulae and weights (or number of mmols) of starting material and product. Formulae are correctly parsed and displayed with numeric subscripts (not common in HyperCard). The yield is calculated automatically. Additionally, element percentages for the chemical formulae are automatically calculated and displayed. A short report is automatically generated in Royal Society of Chemistry or American Chemical Society experimental section punctuation styles. The user may also elect to calculate the isotope pattern of chemical formulae. Some 50 different pseudo-elements such as Me, Ph, Cp, etc. are allowed in chemical formulae.
This stack is shareware and the author retains copyright, all rights, and makes every possible disclaimer (see stack for further details and documentation). You may use this program for 10 days free of charge after which you must pay the shareware price. The shareware price is the same for an individual as for unlimited copying within a site (such as one chemistry department). So you may as well get your Department to pay. The cost per site is £20 (UK pounds) or $40 (US dollars) or the equivalent in your local currency of $40. The markup is for bank charges and air-mail. A nominated member of your department will receive updates and/or notification of upgrades. If you need to know whether your department is registered, contact the author.
The stack is one component of the forthcoming “MacElements” package, a periodic table database HyperCard application with plotting and export abilities, together with various other utilities (such as the ability to calculate yields and isotope patterns!). MacElements is coming real-soon-now.

Cosmetic changes
Fixed an obscure rounding error
1.00 (17/6/93)
Chemical formulae are displayed with subscripts using the Sheffield font.
Brackets []{}() are allowed in chemical formulae and are parsed correctly.
Pseudo element handling is via an XFCN and a “Seud” resource.
Contains a little colour.
Includes some stack self-integrity checks.
ß1.00 (a while ago)
First version was beta, only did isotope patterns, and was called
“HyperIsotopePatterns”.

I understand that receipt of payment will be acknowledged. I will receive one significant upgrade, if there is one, free of charge, together with upgrade notices. I understand that making this shareware payment means that an unlimited number of copies of this program may be made for use within my registered site. This includes “at-home” use for staff and registered students (until their graduation) of my site.
