Appendix B NEMETH DATABASE

This Nemeth database has the conversions for most commonly used mathematics sysmbols. All these conversions should be used inside the CZ editing mode in the WordPerfect, to be translated exactly.

Please make sure you close the exact translation mode by including $tx[sp] after the Nemeth Code. Use the blank sheet to write down the symbols you come across that are not in this database, and we will update it every month.

This database is arranged in alphabetical order. For exam ple to find code for � you can either check mu, or Greek Alphabet.

Note: Each column is seperated by two hyphens.

Letter sign    	   ;	     Need to use single letters, so that they are not 
confused with contractions.  For example single letters like g as in grams, m as in 
meters all should have letter indicators.   Single letters left in text will be translated by 
Duxbury, but inside nemeth code, we should nclude letter indicator. Example: A = l is 
$cz;,a.k#1$tx  Lower limit   limit  %lim Matrices	 [1   2]   @,(#1  #2@,)	Alignment is 
very important.

Subscripts     	   ;	     Baseline indicator " is not needed when there 
s a space after script. For ex. 2cr is #2;cr[sp] also subscript indicator is not when the 
subscript is entirely a number.  For example H2O but not ,h;2",0

Subscript with subscript	  ;;  The second level subscript should be 
represented by two semicolons.

need to use % sign and then as shown in the code.

is a space after the superscript. For example  x2[sp] is x^2[sp] and x2 + y2 is x^2"+y^2

Times  	 x    	   @*	     When you need times instead of 
multiplication symbol use @* Dont use spaces.

Uppercase      	   ,	     For chemical formulae use uppercase symbol 
before each letter. For example HCN is ,h,c,n but not ,,hcn.

Uppercase lock  	   ,,	     To show the whole word is uppercase.
