    $if{$existsVariable{value}}
      {
      $incVariable{value}
      }
    and is equivalent to the expression

      {
      $setVariable{value}{$add{$getVariable{value}}{1}}
      }
    or equivalent to the expression

      {
      $setVariable{value}{$inc{$getVariable{value}}}
      }
The following expression adds the variable named 'value' and the number 7

      {
      $incVariable{value}{7}
      }

    $if{$existsVariable{value}}
      {
      $setVariable{value}{$add{$getVariable{value}}{7}}
      }
    or equivalent to the expression

    $if{$existsVariable{value}}
      {
      $for{$set{counter}{0}}{$less{counter}{7}}{$incLocal{counter}}
        {
