Proper Technique of Setting Config Values

[Archangel]

Darrel showed me to do it this way in PBP, not PBP3 :
16F690

@MyConfig = _INTRC_OSC_NOCLKOUT & _WDT_OFF & _PWRTE_ON  
@MyConfig = MyConfig & _MCLRE_OFF & _BOR_OFF & _FCMEN_OFF & _IESO_OFF 
@ __config  MyConfig

What is the proper technique for setting configuration values?

The proper way is described in the manual and for a 16F part it IS the "one liner". Back in the day MELABS had their own assembler for which the @ DEVICE stuff you reference was used. PM is now obsolete and you need to use whatever Microchip dictates for their MPASM. The manual states:

Microchip determines the form and syntax of the actual configuration directives, and they are not consistent for different families of PIC microcontrollers.

So, with PBP3 and a 16F part you do it the one line way, for the 16F684:

#CONFIG
   __config _INTRC_OSC_NOCLKOUT & _WDT_ON & _MCLRE_ON & _CP_OFF
#ENDCONFIG

Which, I suppose you could "extend" to what Arcangel is showing (not tested and IMHO more cluttered than the oneliner)

@MyConfig = _INTRC_OSC_NOCLKOUT
@MyConfig = MyConfig & _WDT_ON
@MyConfig = MyConfig & _MCLR_ON
@MyConfig = MyConfig & _CP_OFF

#CONFIG
   __config MyConfig
#ENDCONFIG

For 18F parts it's more like the way it was with the PM assembler:

#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

Reply: It IS more cluttered BUT for those who have both poor vision and do not use a wide
screen monitor it allows you to string
the configs across several lines . . .
And it IS tested, I use it on a regular basis. I have PBP3 but use PBP2.6c mostly because I use simpler PICs
and do not want to fritz with PBP3 s configs . . .

Well, I did ask but am disappointed.
Yes, that alternate method is even more cluttered and confusing.
Raises more rule questions than the awkward but more clearer one-liner.

Not being as sophisticated as you all, I strive for consistency in formatting,
hoping that anything "messy" has not been thought through yet by me.

Thanks!

Well, you can always use the U2 Melabs programmer and the software that comes with it. It is very easy to use.

If you you use the programmer to set the fuses, how do you remember what they were 3 months later?
