Bit Array

Questions around writing code and queries

Hi,

Anyone out there have a function suite to set/clear/test bits in something like a DATA item?

I'm currently implementing a bitmap as a dataset but hitting performance issues.

Yours

Hi Allan,

Have you seen Richard Taylor's blog on Bit Fiddling? There may be something there that you can use.
