JL235	I just started learning and messing around with C++, mainly cos a free copy of Virtual Studio 2005 pro has been sitting on my desktop for a while (it is a legit copy, Microsoft are giving free software to university computer students). But anyway I'm trying to make some .dlls of previous code I used in other projects to see it I could get them to work faster, which is all going fine except I'm stuck on one bit of code. What is the equivalent of '$ff3333 Or $ff' in c++? in Blitz it returns 16724991 (and what is it doing too) but in c++ it returns 1, pressumably doing a boolean expression.

Jayenkai	Hex numbers are anything with 0x in front. eg, 0xFF3333 Oct numbers seem to be any number with a 0 at the start. Or at least that's what I found when lining up my code neatly, and then having C++ whinge at me, that 09 wasn't a number! -=-=- ''Load, Next List!''

JL235	I meant of the 'or' bit, cos it isn't being used as a logic opperator in that example. I did work it out though thanks to wikipedia. There is a whole page for the opperators in c and c++. I managed to get my .dll that works out an alpha formula working though, although it works slower then if I just did it in Blitz which is dissapointing, but maybe not suprising. But I did find it alot easier to work out and get to grips with the I thought I would. I've never made anything in c or c++ before, and never a .dll either. It'll be cos it's so similar to Java though.

Yayyak	'I' is bitwise or, operating on the individual bits. 'II' is a logical or, evaluating both expressions and if one is true, then it returns true. If that doesn't work, try them round the other way.

Jayenkai	It's not I, it's \|... The bar thing, next to Z (or at least on my keyboard!) It used to do "\|Tape", "\|Disk (or was it disc)", "\|CPM" and other stuff, on the CPC. \|User 12 Run "diary Shhh -=-=- ''Load, Next List!''

Yayyak	Oops. I can type, honest. I looks so close to \|, in the reply box. But yes. Do what Jay says, and you won't go wrong! Edit: My \| key is above the return key. How odd.

Jayenkai	The CPC's \| is next to the P.

Yayyak	IIRC, it was originally called the vertical bar, and this is it's proper name. The UNIX dudes (Bourne & Thompson specifically) took this bar and used it for the syntax for the UNIX 'pipe', hence the name.
