assign multiple derivations in a transformer

[seanc217]

Hi there,

I was wondering if you could do something like this in a transformer:

if x =1 then
a = "1"
b = "2"
else
c="3"


The key being the multiple assignemnt of a and b.

Hope that's clear.

Thanks

Use stage variables.

I dont think the assignment statement will be valid .write seperate derivations for each variables else you should be getting the expression in

No. Multiple assignments are not allowed. As Ken pointed out, use stage variables. Feel free to use as many for as many assignments.

Beware that you must assign a value irrespective of the test. So you need to decide values for variables a and b when x <> 1, and for c when x = 1. Sometimes you need to leave the value unchanged; in this case assign the stage variable to itself. For example, consider a stage variable svCounter that counts the product codes. It might be initialized to 0. The it might be derived as

Code: Select all

If svProdCodeChanged Then svCounter + 1 Else svCounter
