Hello Everyone, For some reason I am drawing a blank on this. It’s something I haven’t had to deal with for a long time. Scenario: Say I have multiple possible “flags” stored as Equates. For example: FlagOne Equate(1) FlagTwo Equate(2) FlagThree Equate(3) FlagFour Equate(4) FlagFive Equ…

[image] vitesse: TpsLong = bor(TpsLong, FlagTwo+FlagFour) The most correct code is to not use Addition or Subtraction when doing Boolean. Instead: TpsLong = bor( bor(TpsLong, FlagTwo), FlagFour) Or: TpsLong = bor(TpsLong,FlagTwo) TpsLong = bor(TpsLong,FlagFour)

I agree completely, but sometimes it’s just easier to add the stuff up. Like with FILEDIALOG(), for example. Nobody ever BOR’s those switches (FILE:Save+FILE:KeepDir+FILE:LongName, etc).

Stumbled across an interesting video explaining bitwise operators: [image]

I use the BitList control template from ClarionMag… It has great features [image]

Maybe you would find this useful for visualizing how bits are laid out in a hex digit. I guess I should have made it go right-to-left, but I kind of like it like this. [Counting in Hex]

[image] jslarve: Like with FILEDIALOG(), for example. Nobody ever BOR’s those switches (FILE:Save+FILE:KeepDir+FILE:LongName, etc). I agree. Another good example of Bit Maps is the Message Button Equates. They also can be added: BUTTON:OK EQUATE (01H) BUTTON:YES EQ…

Basically, I think a good rule of thumb could be this: If you are modifying existing values, you should ONLY use the appropriate bitwise functions. If you trust that your bits won’t clash, and you are starting with no value (e.g., you are creating the mask value from scratch), and you don’t add th…

[image] jslarve: IF we could use a “|” instead of “BOR()”, like in javascript, then BOR would be a lot more sexy than adding, but all of those parens get BORing. Agree. CW Utils should have a functions for And/Or/Xor that take more than 2. This should work… BOrMany PROCEDURE(LONG pValue, LO…
