help about error messages

Hello
i'm just approaching to pic programming and i tried to compile a .bas file. Compiler give me a lot of error such as

C:\PBP\16F684.BAS ERROR Line 135: Bad expression.
C:\PBP\16F684.BAS ERROR Line 155: Redefiniton of LABEL CCP1CON.
C:\PBP\16F684.BAS ERROR Line 157: Redefiniton of LABEL CCP1CON.
C:\PBP\16F684.BAS ERROR Line 166: Redefiniton of LABEL CCP1CON.
C:\PBP\16F684.BAS ERROR Line 168: Redefiniton of LABEL CCP1CON.

pic is 16f684

could someone help me to understand the error meaning, or is there a manual or other where i can study the meaning of error?
Thanks
Alezz.

Hi, Fourtech

Could you provide the full program you've written ???

This is the minimum requirement for the crystal ball to light up ... :barbershop_quartet_

seriously, looks to be a small typo somewhere ...

Yes, likely a typo in line 135 but could be elsewhere

following the code that i tried to compile

End

Compiles fine over here. At least for a 16F684.

Grenade compiles fine here too ... :angel:

Rename your source file to something other than the part number.
PBP need to include a file named 16F684.BAS from the PBP folder.
But instead it includes your source code again. Creating many duplicates.

Hello Mr. Darrel
thanks a lot for you suggestion
did You pbp 2.6 or 2.4 for compiling the code, I'm tring to use pbp 2.6 under melabs ide 8.76.
