Which three statements are true about Transformer stages? (Choose three.)

  1. Derivations are written in C++.

  2. Constraints are executed before output link derivations.

  3. Stage variables are executed before output link derivations.

  4. @PARTNUM returns the number of job partitions currently active.

  5. Constraints can keep a record from being written to an output link.

B,C,E Correct answer
Explanation

Execution order in Transformer: stage variables first, then constraints, then output link derivations (B and C are correct). Constraints filter records (E is correct). Derivations use BASIC-like syntax, not C++ (A is wrong). @PARTNUM doesn't exist in DataStage (D is wrong).
