Here are a few examples of how to use the new #CONFIG block syntax for PBP3. (This will NOT work on previous versions of PBP ... Get your upgrade now 
)
PBP3 makes it a little easier to figure out, and set up your configs. It has eliminated the need to comment out the default configurations set up by PBP. It still has default settings - these can be found in the /PBP3/DEVICES file under yourchip.PBPINC . Here is an example of default settings for the PIC18F45K22:
Code:
; CUT rest of file out for display purposes
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
; The #CONFIG block is passed directly to the asm file, but PBP will replace it
; automagically with the contents of a user-defined #CONFIG block if one is
; found in the PBP source program.
#CONFIG
__CONFIG _CONFIG1H, _FOSC_INTIO67_1H
__CONFIG _CONFIG3H, _PBADEN_OFF_3H
__CONFIG _CONFIG4L, _LVP_OFF_4L & _XINST_OFF_4L
#ENDCONFIG
; CUT rest of file out for display purposes
If you want to change the default configs in PBP3, DON'T edit the above file. You can just declare them in your code using the #CONFIG #ENDCONFIG block. For all the possibilities of config settings for your chip, check out the /PBP3/DEVICE_REFERENCE folder, and select the yourchip.INFO file. It will look something like this:
Code:

If you get an error like:
[ERROR] program.pbp fatal (34) : Block overflow for #ENCONFIG
that means that there are too many comments in your configs to "fit". Erase some comments and try compiling again.
Some new features in PBP3 make it possible to do conditional defines, and conditional PIC setup.
(Some content plagiarized from here: http://support.melabs.com/threads/26...wfull=1#post38 ... Thanks Darrel!)
Here's an example of how you can set the configuration bits according to the chip being compiled for.
It uses the Conditional Compile directives (#IF/#ELSE/#ENDIF) along with the #CONFIG blocks.
Only the configs for the selected chip will be used.
And if any other chip besides the 25K20 or 25K22 are selected, it will give an error.
Code:
#IF __PROCESSOR__ = "18F25K22"
#config
CONFIG FOSC = HSHP
CONFIG WDTEN = OFF
CONFIG PWRTEN = ON
CONFIG BOREN = OFF
CONFIG PBADEN = OFF
CONFIG MCLRE = INTMCLR
CONFIG LVP = OFF
CONFIG DEBUG = OFF
CONFIG XINST = OFF
#endconfig
ANSELA = 0 ; All Digital
ANSELB = 0
ANSELC = 0
#ELSE
#IF __PROCESSOR__ = "18F25K20"
#config
CONFIG FOSC = HS
CONFIG WDTEN = OFF
CONFIG PWRT = ON
CONFIG BOREN = OFF
CONFIG PBADEN = OFF
CONFIG MCLRE = OFF
CONFIG LVP = OFF
CONFIG DEBUG = OFF
CONFIG XINST = OFF
#endconfig
ANSEL = 0 ; All Digital
ANSELH = 0
#ELSE
#ERROR "This program does not support the " + __PROCESSOR__
#ENDIF
#ENDIF
Note that it also sets the ANSEL? registers differently for each chip. Anything else specific to a particular chip can be set this way too.
Some things to remember:
PBP can not use the XINST ,"Instuction set extension and indexed addressing mode", so make sure it is never turned on.
LVP is another issue. Just leave this off as well.
Some older chips like a slightly different context. Let's take a PIC16F628A for example:
Here are the default configs:
Code:
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
; The #CONFIG block is passed directly to the asm file, but PBP will replace it
; automagically with the contents of a user-defined #CONFIG block if one is
; found in the PBP source program.
#CONFIG
ifdef PM_USED
device pic16F628A, xt_osc, wdt_on, mclr_on, lvp_off, protect_off
else
__config _XT_OSC & _WDT_ON & _MCLRE_ON & _LVP_OFF & _CP_OFF
endif
#ENDCONFIG
(The first part of this conditional config statment checks to see if the PM assembler is used. Since code for the newer chips can't be assembled with PM, I always chose MPASM.)
You have to use a format like this for these older chips: __config _x & _y & _z
