Alright, so that clears it as far complex derivation is concerned in a single expression cell. Disappointing but that's what it is.ray.wurlod wrote:However, multi-statement blocks are not available in expressions; indeed no form of statement is available in an expression.
Forget my example for a second Ray. Basically, what you're saying is that if I had 5 input fields mapped to 5 output fields and each input field required 5 manipulations before being mapped to those 5 output fields, I would need 25 stage variables if I wanted to be clean?ray.wurlod also wrote:I continue to maintain that your example could be done in a single expression with no stage variables. But using stage variables would make it easier to understand and therefore more easily maintained.
By the way, thanks for the replies to all who contribute on this site. Your knowledge is appreciated.
