[MI-L] MapBasic Bitwise Operators

Title: MapBasic Bitwise Operators






Hi All,


I am wanting to use bitwise operators in MapBasic, but I can't find any information on them.


Does anyone know if the exist and how to use them, or do I need to write my own functions?


Cheers Ian

You have to write your own, but it's pretty easy. For example, to test the
5th bit from the right in an integer use integer divide and mod like so:

n = 5
if nBitflags \ 2^(n-1) mod 2 then
  ' bit is set

MB does not do true bit operations
I have a dll with a whole lot of delphi functions built in it
you can get it here http://www.wap3.com/download/ultramsg.zip

does string math like s=(5+2)*3 and gets back the answer
does HTLM output  better than that dumb message window
and a lot more
