Question regarding pagesel

I am hoping that someone can confirm something for me. I have a pic program (assembler) that contains the following code snippet:

DECFSZ X, 1
pagesel rept
call rept
retlw 0

If the result of line 1 is zero, the next instruction is skipped. This means that "pagesel rpt" is skipped and rpt is called, correct? This means that pagesel cannot be used following commands such as "DECFSZ" or "BTFSC"?

DECFSZ is a bit test on a certain register.

If the result of the test is zero, the next instruction is skipped as you have said.

If the result of the test is NOT zero, the next instruction is not skipped but executed.

You can use any instruction following a test.

You are correct, a better way to write it would be,

Mike.

Nothing wrong with the 'pagesel' assembler directive, you're just using it completely wrongly! - it's NOT a PIC instruction, it's an assembler directive and creates more than one line of code, which makes your misuse of it fail badly.

Thanks for the replies. This was helpful.
