- This version of MacFormula fixes a few bugs in
- earlier releases, and offers a few major enhancements. For
- instance, MacFormula will no longer choke trying to find
- the exact mass of sulphur.
- You can now modify the values of the elements that
- MacFormula uses to find the formula weight of a
- string (Yippee!). You can also enter your own symbols (like
- D(ueterium), Ph(enyl), Me(thyl), etc). I hope you enjoy
- this feature. Total symbols, including the periodic table
- may not exceed 150. This is explained further in “Creating
- your own symbols.”
- MacFormula will now calculate the elemental
- analysis for all of the elements in your formula (up to a
- total of 20).
- The source code for MacFormula has been totally
- rewritten. As a result, MacFormula now runs a bit
- faster.
- Known Bugs
- • This is more of an anoyance than anything, but if an
- edittext item is hilited, or if the blinking cursor is not
- at the end of the string, and <CR> or <RETURN> is hit
- instead of the “Calculate” button, MacFormula will
- return “Bad Input” as the formula weight. This is because I
- am using TransSkel library routines and they don't allow
- interception of dialog events for modeless dialogs.
- Really...it's not my fault. This will not happen to you if
- you don't hit <CR> or <RETURN> twice in a row without typing
- anything, or if you move the blinking cursor to the end of
- the string after making an insertion in the middle of the
- string. It will never happen if you always use the mouse to
- press the “Calclulate” button.
- Future Plans
- So far no one has contacted me concerning any ideas or
- items they would like to see implemented in MacFormula.
- This is probably because they are embarassed that they have
- not mailed in their shareware payment. Quite truthfully, I
- have received very few payments, when I know that, in fact,
- quite a few people are using MacFormula in their work.
- With that in mind, it is very difficult for me to justify my
- time working to make MacFormula better. I would like to
- include a provision for parentheses, and perhaps allow a
- user to print out an elemental analysis request form with
- everything filled in. Whether or not any of these things
- happen is entirely up to you...the user.
