Beginer PIC´s Quiestions

[SISKO]

Im learnig PIC programing and this is going to be a post where im going to post questions about it as they arrive to me while learnig or reading some book.
The first one is:
Say i want to set PORTB as outputs, so i write:

ptob          equ      0x06
start         movlw   h"0"
                tris       ptob

Now, is it a must to loada number on the W registry (movlw) whenever i want to load it on any memoy adress?

What PIC you will be using? Assuming is a PIC16F then it will go like this:

        bsf          STATUS,RP0   ; Bank 1
        movlw     h'00'
        movwf     TRISB
        bcf          STATUS,RP0   ; Bank 0

or

        bsf          STATUS,RP0   ; Bank 1
        clrf         TRISB
        bcf          STATUS,RP0   ; Bank 0

There are a lot more so you can search for it on the web.

Good luck,
