2.4. VARS Section 

It  contains  variables,  processing  the  parameters  and  other  calculations  (e.g.  the  sum  of  the  parameters).  The 

lines in this section are in ascending order, starting from zero. Each line has the following format: 

 

<index> <source type> <argument 1> [argument 2]

 

 

Index: the sequential number of the line. 

The types of the arguments: 

 

<bit number>

 - is the bit number of the parameter from 0 and above. For 16-bit parameters it is no more 

than 15. For 32-bit parameters it is not more than 31;

 

 

<int

>

 - 32-bit signed integer;

 

 

<param ref>

 - parameter reference of format Pn, where n is index of the parameter;

 

 

<var ref>

 - variable reference of format Vn, where n is index of the variable.

 

 

<cond ref> - 

reference to the Cn format condition, where n is the condition index
