Here's a tips on how to mix ASM and PBP.

        '    Using PIC16F88
        @ DEVICE INTRC_OSC, LVP_OFF, WDT_OFF, MCLR_OFF
        
        DEFINE OSC 4
        OSCCON=%01101000
        ANSEL=%00000000
        CMCON=%00000111
        
        trisa = %11111111
        trisb = %00000001
    
        DEFINE HSER_RCSTA 90h ' Enable serial port & continuous receive
        DEFINE HSER_TXSTA 24h ' Enable transmit, BRGH = 1
        DEFINE HSER_SPBRG 25  ' 9600 Baud @ 4MHz, 0.16%
        DEFINE HSER_CLROERR 1 ' Clear overflow automatically
            
        CounterA    var byte BANK0
        CLEAR
        
Start:
        asm
                CHK?RP PORTB
                BTFSC   PORTB,0
                GOTO $-1
                INCF _CounterA,F
        ENDASM                
        HSEROUT ["CounterA=",DEC CounterA,13,10]
        PAUSE 200
        GOTO START

You define your variable in PBP, then you access them in ASM. Possible to use the other way... BUT not 100% sure if this is safe though... sure it isn't 'cause you can't know for sure where PBP will place it's own variables.
