Evaluates the text argument as an EasyMorph expression. The argument itself must not be an expression with a reference to column.


  eval('1+1')           //Result is 2.
  eval('1' & '+1')      //Result is 2.
  eval('max(1,2)')      //Result is 2.
  eval('[Count]+1')     //Evaluated as [Count]+1.
  eval([Count] & '+1')  //Invalid! References to columns are not allowed in argument expressions.
  eval({Param1})        //If the value of {Param1} is '[Count]+1' then it's evaluated as [Count]+1. Parameter references are allowed.
  eval("1+" & "eval('1+1')") //Result is 3. Nesting eval() is allowed. 

The eval() function makes it possible to define EasyMorph expressions externally using parameters.
