The files in my assembler's folder are *.epc, so not exactly what is discussed in the post you have forwarded. For instance, in my PIC16F777 file is the following;

ConfigLoc=0
ConfigBase=0x3fff
ConfigMask=0x31ff
GroupName="Oscillator"
GroupMask=0x0013
ItemName="EXTRC ClockOut"
ItemValue=0x0013
ItemName="EXTRC"
ItemValue=0x0012
ItemName="INTRC ClockOut"
ItemValue=0x0011
ItemName="INTRC"
ItemValue=0x0010
ItemName="EC"
ItemValue=0x0003
ItemName="HS"
ItemValue=0x0002
ItemName="XT"
ItemValue=0x0001
ItemName="LP"
ItemValue=0x0000

I assume the "group mask" is the setting used if not otherwise defined. I do not understand how to change these in the @ define statement. Thanks for your help!
