-**FIXME** This will be used to describe the new tab on cache details used for cache variables. 
- 
-**FIXME** We could add a chapter with some practical How-To examples (e.g. typical lettervalue case)

   * ''[0-3, ^1-2, 5]'' evaluates to a range containing ''0'', ''3'' and ''5''.   * ''[0-3, ^1-2, 5]'' evaluates to a range containing ''0'', ''3'' and ''5''.
  
-When a range is used in a context where only one value is allowed (this is the case in normal calculation), the first range value is used for calculation. For example, the expression ''[8, 0-9]'' will evalulate to ''0'' in a normal calculation context, while ''[8, 0-9]'' will evalulate to ''8''.+When a range is used in a context where only one value is allowed (this is the case in normal calculation), the first range value is used for calculation.

 Ranges currently support only positive constant integer values. A range must always be evaluate to at least 1 value and a range may not evaluate to more than 20 values. For example the following ranges are invalid: Ranges currently support only positive constant integer values. A range must always be evaluate to at least 1 value and a range may not evaluate to more than 20 values. For example the following ranges are invalid:
Line 215: Line 211:
   * ''A*[4, 7]'': for ''A=3'' this evaluates to values ''12'' and ''21''   * ''A*[4, 7]'': for ''A=3'' this evaluates to values ''12'' and ''21''
   * ''[1-2]*[3-4]'': evaluates to ''3'', ''6'', ''4'' and ''8''.   * ''[1-2]*[3-4]'': evaluates to ''3'', ''6'', ''4'' and ''8''.

 +==== Comments ====
 +
 +You may enter comments into formula expressions using the ''#'' character. Comments end at next ''#'' or at end of expressions. Everything in a comment is ignored during evaluation. For example:
 +  * ''A * 5 # test comment'' for ''A=3'' evaluates to ''15''
 +  * ''3.14 # this is pi # * 2 # and this is two'' evaluates to ''6.28''
