Scheme of a chemical process consists of equ-
ations ( marked with any symbolic identifier 
at the end of line) of chemical reactions  of
zero, first, second or third order (One at  a
line).                                       
Reagents and products should be presented  by
identifiers (6 symbols significance).        
'=', '+' used as delimiters.                 
When reagents are put  in  ()brackets  in  a 
reaction, rate of the reaction is assumed  to
be uneffected by their  concentrations,  i.e.
this does not alter reaction's order  (though
reagents will be consumed).                  
When products of any reaction are of no inte-
rest (importance) you may omit right part  of
equation (and '=').

Reagent's names and rate constants of current
variant are permitted in expressions.        
Reag.'s name means its initial concentration.
     You should know that all data input is  
carried out through Calculator. Try this.    
           Anamorphose :                      
  Default look_over mode is concentration/rate
vs. time. You may change axes to any permitted
(see Calculator) expressions.                 
  To refer to reagent's rate consumption use  
apostrophe (e.g.  A').  To  refer  to certain 
concentration's/rate's value use indexation[].
  Number and position of calculated points can
be inquired about in a table-mode  or  by tur-
ning switch "Smooth" off.                     
  NB!!! To avoid zero dividing in  anamorphose

tions and so,  set  desired  range  of  kinet.

  Here are two reserved words  -  TIME  (refe-

            Input :                              
  To enter a value start typing number or expres-

To edit previously inputted value  press  [Enter]
ahead. End of input - [Enter], refusal - [Esc].  
  Any reagent's  initial  concentration  or  rate
constant may be marked with [Ins] for the optimi-
zation. Moreover, there is possibility (in calcu-
lations, not in life) to prevent consumption of a
reagent  (make  its  concentration  constant   in
calculations). Choose such  reagent  with  [Del].
Chosen reagents (rate constants)  are  marked  on
the screen with '*'  and  'C'  respectively.  All
choices denied by repeated press of the keys.    
        In TIME section are inputted :           
 StepM - step of output. Results'll be written on
a disc after every StepM seconds of virtual time.
 Total - total  time  of  simulated  process.
