VAR <list of variables> TO <data> 
with transformation statements written in the same edit field and
defining values for the variables in the list specifies
simultaneously several transformations and definitions of variables
as functions of other ones.
If a variable in the <list of variables> does not exist, it will be
automatically created provided that there is enough space in <data>.

Example:  (Data RECTANGLS includes variables 'Width' and 'Height')
VAR Area,Diagonal TO RECTANGLS
Area=Width*Height
Diagonal=sqrt(Width^2+Height^2)

Conditional statements may appear as follows:

VAR Ageclass:1 TO SAMPLE_3 / 'Ageclass' will be a new one-byte variable
    Ageclass=if(Age<26)then(1)else(A2)
          A2=if(Age<=60)then(2)else(3)

To avoid confusions, it is advisable to protect all those variables
whose values must not be altered.
