Bitand

[Andy Powell]

Thanks Rob!

I did that and both machines return the same result for sys(205) which is 0 little-endian apparently. However, below shows new developments...

I think it's something to do with the variable types now. We were using a comms object provided by a credit card processing company that returns this value as a number in the object so we were doing

If bitand(lv_oObject.$supports,4)=4

Now, I've changed it to use a row which is populated from a webservice. The variable type in this row is a Long number just as the comms object stated it was. 

On my PC (the i7 blah blah) it works however on the server the same number returned a 1 (where it should have been a 4). 

Anyone with any experience with all of this bit stuff, do I need to do any conversions to binary types of anything like that? I wouldn't had thought it would make a difference but apparently it does? 

Thanks again everyone.

I would have thought if you are running in Omnis, Omnis will be working with 32 bit throughout - so should be the same.

;  sys(110)     ;; CPU type
;  sys(205)     ;; byte ordering of hardware

test sys(205) on each machine and see if you get the same result.

Failing that 32/64 bit *might* have something to do with it - but I really don't think so.
