Case('RS.IntermediateRes' > 5.5;"Intermediate result too
high";'RS.IntermediateRes' * 26.5;"Error occurred") = If the result
"IntermediateRes" is greater than 5.5, the text "Intermediate result
too high" will be written into the result, otherwise the intermediate result
will be multiplied by 26.5. If an error occurs during the comparison
('RS.IntermediateRes' > 5.5), "Error occurred" will be saved as a
result of this operation.

Parameters
Value
