The range operator is denoted by double periods .. inserted between 2 integer expressions.

It is usually used in conjunction with the membership operator in [] to test if an expression belongs to a set of values.

bisallowedspeed = nspeed in [30..90] // in europe

The range operator can also be used in a switch statement.

switch nAge
   case 13..19
      sRESULT = 'teenager'
   case 50..59
      sRESULT = 'in the fifties'
endswitch

It is important to note that special character markers are treated as single characters.
