Hi there,

Does Datastage provide bitwise op? Can you get the highest 2 bits of a byte and then 4 bits, then the lowest 2 bits? I.e., a byte data is split to three parts: highest 2 bits, middle 4 bits, lowest 2 bits with Datastage?

Thanks,

Always best to check Appendix B of the Parallel Job Developer's Guide for currently available built-in transform functions.

Having said that though, I don't recall any.

If you can afford to use a BASIC transformer in a parallel job or a BASIC routine in a job sequence, I'm pretty sure there are BASIC functions that can test and manipulate bits.

They are described in the location Mike indicated, and under the Logical functions section.

BitAnd(), BitCompress(), BitExpand(), BitOr(), BitXOr(), Not(), SetBit()

I would think you need to use the BitAnd() function.

Thanks a lot. So bitwise op can be done with BASIC, but for parallel, we have to use C to manipulate it, even it's hard. I just wonder why bitwise logic op is not provided as a stardard ligocal op. It's easy to do so.

Thanks,

Seems to me that BASIC isn't needed. I would think the parallel transform functions listed by qt_ky should give you what you need.

Exactly, you seem to have misunderstood the reply - those are the built-in Parallel Logical bit-wise functions he listed.
