PrettyChemical v2.03

(from Screetch with thanks to Dietmar, 2000-08-19)

Installation: download 'HP48_PrettyChemicalV2_03' and save it as 'PC' or whatever you want in any port or directory. To run the program proper you need the Universal Font Library 'ufl.hp', which you can find in the zip file and has to be ATTACHED to the HOME directory (see http://www.hpcalc.org/apps/editors/fonts/ufl102.zip for further information).

Usage: ".." <PC> or PC [ENTER]

Syntax#1

"Left1+Left2+LeftN®Right1+Right2+RightN"

Output#1 in pretty print (between the components and + and between the components and the arrow a space will be added.)

Left₁ + Left₂ + Left_N ® Right₁ + Right₂ + Right_N

Syntax#2 (remark the required spaces between the last component and Up1 and the first component after Down.)

"Left1+Left2+LeftN Up1+UpN_®_Down Right1+Right2+RightN"

(or only ".. Up1_®.." or "..®_Down ..")

Output#2 in pretty print

Up₁ + Up_N

Left₁ + Left₂ + Left_N -----------> Right₁ + Right₂ + Right_N

Down

· Left_X, Right_X and Up_X are pretty printed and therefore the following syntaxes recommended:

- size unlimited indices (printed in subscript); e.g. "C12H22O11" -

example 1 or 2

- use [ ] and ( ) as you want; e.g. "K2[CoFe(CN)6]" - example 1

- everything in {curved parenthesis} will be printed in superscript; e.g.

"Na{+}" or "C{+IV}" or "1s{2}" - example 1,4 or 5

- as indicator for crystal water use *; e.g. "MgCl2*6H2O" - example 6

- as indicator for radicals use .; e.g. "Br." - example 3

- instead of spaces use _; e.g. "1s{2}_2s{2}" - example 3 or 5

- use R’’-COOH or R’CH3 for organic chemistry; example 2 or 3

· Down will be treated as text and therefore you are able to use all characters you want, but you have to use "_" instead of spaces (all spaces are ignored completely); e.g. 100_-_200°C - example 2

PrettyChemical works with the system font or the minifont (from the ufl). The following flags influence the output:

user flag clear* set

#1 Left, Right are printed with the current mini font

#2 Up, Down are printed with the mini current font

(*default)

examples (flag #1 cleared and flag #2 set; pictures are captured after use of SCROLL with a HP49G):

1) "4Au+8CN{-}+O2+2H2O®4[Au(CN)2]{-}+4OH{-}"

2) "2R-X+CH2(COOR')2 C2H5O{-}_®_alkylation R-CH(COOR')2"

3) "2R-COO. -_2CO2_®2R."

(remark:you have to use ".. -_2CO2.." instead of ".. –2CO2..")

4) "Ca{+II}C{+IV}O{-II}3"

5) "C_1s{2}_2s{2}_2p{2}"

6) "Na2SO4*10H2O"
