I know this is back-asswards, but I'd like to know how to do this in C/C++

Let's say I have a ceiling color value of 133, read from a map tile. I want to be able to plug that into the DOS EXE so it will display the correct color ceiling. I can do it easily in SDL because there it just uses straight values in drawing the ceilings.

In DOS, because we are using assembly code and for some reason, need to duplicate each color (or else get striped ceilings), it looks like the following needs to be done:

1) convert the decimal value to hex

2) concatenate the hex value with itself

3) plug this result into 'ceiling' in WL_DRAW.C

In this example, 133 is 0x85, and I want to use 0x8585 to draw the DOS version ceiling.

How do I code this in C/C++? And does this even make sense?

There's a few code examples here:

For reference: 133*256 + 133 (ceiling<<8 + ceiling) = 0x8585

Thanks again, Chris!
