(New trap in propeller assembly) Not a trap, Just a typo

stevenmess2004

If you do this

DAT
org 0
'...some code
aLabel
     MOV 0,0
anotherLabel
     MOV 0,0

org aLabel
:otherLabel
    MOV 0,0
    MOV 0,0
    MOV 0,0
    JMP #:otherLabel

The compiler complains that it can't find otherLabel at the JMP line. I presume that this is because anotherLabel breaks it up into a different section. Just something to watch out for if you are doing overlays.

Steven,

This seems to compile fine. And it looks fine, too. I'm using version 1.05.8.

Sorry Chip,
I tried to cut it down to something simple and didn't check it...

Anyway, this file shows the problem. Right down near the bottom there is a line with the label :loop1 and a bit further down there is a JMP that calls it. If you remove the ':' it works.

I'll try and see if I can find a smaller example or cut this down to the smallest thing that causes the error. I had to add the .txt to upload the file.

Oh, I found it!

You meant to type "if_nz", but you typed "in_nz", which was interpreted as a non-local label:


······················· ADD···· loopC1,#1
······················· CMP···· loopC1,#12····· wz
······· in_nz·········· JMP···· #:loop1

Thanks for that Chip. Sorry to cause you the trouble. Next time I'll check more carefully before posting something.

Edit: Hey Chip, for the propeller II can you add a feature to the compiler so that it knows what you meant to type and not what you actually typed?
