I just wanted to thank every one for their assistance with this problem. I was able to build the lesson code with no further problems. I have gone to lesson 5b and it had the same problem as 5a and wouldn't compile completely. So I went back and entered the org statement that fixed lesson 5a and another problem popped up. I get the following error when I try and build this lesson: MPLINK 4.05 LINKER Copyright (c) 2006 Microchip Technology Inc. ERROR-Section 'org_0' cannot fit the absolute section Section 'org_0' start 0x00000004. Length 0x00000012 Errors: 1 The code is: processor 16f84 include __config _HS_OSC & _WDT_OFF & _PWRTE_ON cblock H'20' spot1 spot2 endc org 0x0000 bcf Status,Z bcf Status, C bcf Status,DC clrf spot1 movlw D'15' movwf spot2 movlw D'03' addwf spot2,F nop end I have the above code formatted correctly in the IDE. I just typed it in this way so it wouldn't run all over the page. Can some one please tell me what the error is and why the org statement would not fix the problem like it did in lesson 5a. I started this tutorial earlier this year and don't recall having any of these problems? I just restarted this tutorial as a refresher and all these problems popped up. The only difference is I am using a newer version of MPLAB v7.43.
