First of all Hi, I'm new. Glad to meet you people.

I am an extreme newbie here. I cannot for the life of me figure this out properly.

I opened the example lcdx for PIC16F877A but I'm stupid, so I wanted to try to compile it for another PIC chip. PIC16F87 to be specific. I'm looking at the datasheet, and found ADCS1 in special register functions.

So naturally, I thought it would just compile for it, but these lines stop the compilation.

Code:
ADCS1 = 7      ' Set PORTA and PORTE to digital
   Low PORTE.2
It says:
For ADCS1 = 7:
Bad Expression
For Low PORTE.2
Syntax Error I think...
Could someone explain to me how this works? I am so confused honestly.

Could someone point me at an instruction set thinger for specific microcontrollers?
