    Hi, Dave and Tim

    I had a look to the TEST section of this program ... It gave that, with a " classic " PBP use. :

    Code:
    'Config
    
    @	__CONFIG    _CONFIG1, _CP_OFF & _CCP1_RB3 & _DEBUG_OFF & _WRT_PROTECT_OFF & _CPD_OFF & _LVP_OFF & _BODEN_OFF & _MCLR_ON & _PWRTE_ON & _WDT_ON & _INTRC_IO
    
    @ 	__CONFIG    _CONFIG2, _IESO_OFF & _FCMEN_OFF
    
    
    
    '@ __config _CONFIG1, _INTRC_IO & _WDT_ON & _LVP_OFF & _CP_OFF
    
    DEFINE ADC_BITS 10 ' Sets the number of bits in the result to 10
    
    
    ANSEL = %00001111 'set RA0-RA3 as analog inputs
    
    'ADCON1 = %10000000 'Right Justifies 10-bit value 
    
    'OSCCON = $60 'Sets the internal oscillator to 4 Mhz
    
    OSCCON 	= %01101110 'Internal RC w/ I/Os
    
    INTCON	= 0
    PIE1	= 0
    PIE2	= 0
    CMCON 	= 7 'Comparators off
    CVRCON 	= 0
    
    INCLUDE "modedefs.bas"
    
    ti var byte
    ti = 50 '20 MILLISECONDS DELAY'
     
    A VAR word
    B VAR word
    C VAR word
    D VAR word
    
    _A CON 0
    _B CON 1
    _C CON 2
    _D CON 3
     
    TRISA = %00001111 
    TRISB = 0 'TURN PORT B as outputs but RB1 WHEN USE ICD FOR COMMUNICATION
    
    '* * * * * MAIN PROGRAM START HERE * * * * * * * * 
    
    PAUSE 1000
    Serout PORTB.1, 0, [254,1] 
    Serout PORTB.1, 0, [254,2]
    PAUSE 20
    
    READSENSORS: 
    
    'ADCON0 = %00000001 'Turn ON CHAN 0 
    'GOSUB ADCON
    
    ADCIN _A, A
    
    'A.LOWBYTE = ADRESL 'PLACES THE LOW BYTE INTO VAR
     
    SEROUT PORTB.1 , 0, ["Ch 0= ",# A.LOWBYTE]
    pause 20
    
    'ADCON0 = %00001001 'Turn ON CHAN 1 
    'GOSUB ADCON
    
    ADCIN _B, B
    
    'B.LOWBYTE = ADRESL 'PLACES THE LOW BYTE INTO VAR
    
    SEROUT PORTB.1 , 0, [" Ch 1= ",# B.LOWBYTE]
    PAUSE 20
    
    SEROUT PORTB.1,0,[$FE,$C0]
    
    'ADCON0 = %00010001 'Turn ON CHAN 2 
    'GOSUB ADCON
    
    ADCIN _C, C
    
    'C.LOWBYTE = ADRESL 'PLACES THE LOW BYTE INTO VAR
    
    SEROUT PORTB.1 , 0, ["Ch 2= ",# C.LOWBYTE]
    PAUSE 20 
    
    'ADCON0 = %00011001 'Turn ON CHAN 3 
    'GOSUB ADCON
    
    ADCIN _D, D
    
    'D.LOWBYTE = ADRESL 'PLACES THE LOW BYTE INTO VAR
    
    SEROUT PORTB.1 , 0, [" Ch 3= ",# D.LOWBYTE]
    
    
    PAUSE 1000
    Serout PORTB.1, 0, [254,1] 
    
    GOTO READSENSORS ' PROVISIONAL LOOP TO CHECK THE A/D CONVERTION.
    I just commented out original lines for comparison ...

    Hope it Helps

    Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

    IF there is the word "Problem" in your question ...
    certainly the answer is " RTFM " or " RTFDataSheet " !!!
