How to add two binary variables next to each other, without mathematical operations?

[CuriousOne]

The question is.

Say I have variable A, which is 1110 in BIN. And have variable B, which is 1101 in BIN. I want to convert them to single variable, which will read as 11101101 in BIN, by just adding them next to each other. If I use "+", then binary values of these variables will be added, so mathematicaly, result will be correct, but this is not what I need.

You need to shift the first variable "up" (to the left) 4 places and THEN add the second variable.

Result = (VAR_A << 4) + VAR_B
But yeah, it IS using a mathematical operator but why don't you want that?

Because this binary variable is actually a pattern for dot matrix led display.

Matrix is 10 pixels wide, 7 pixels in height. So say, I want to display two symbols on it, each are stored in separate variable, I have to place them next to each other :)

I understand that you want to place the two nibbles next to each other within the byte but I don't understand why you want to do it without mathematical operation.
Anyway, try the suggested method, it does what you're asking for.

never mind, it just "lost in translation", your method will work, I believe :)
