    Default Arrays calling Arrays

    My project is to determine the %moisture content of grain in storage. I’m using 1-Wire DS2438 and Honeywell HIH-4000 RH sensors inside of the grain. I have a number of sensors on each string. All devices are working good using individual SN to address each device. I have ample RAM but I’m running out of CODE space. To reduce the program size I need to be able to use an array of some kind to be called by a variable residing in the routine to address each 1-Wire device in secession so I can loop through a single routine rather than have multiple routines. Instead of using:
    Code:
    OWOUT  DataPin, 1, [MatchRom,$26,$7A,$BA,$11,$01,$00,$00,$D8, ConvertV]
    I would like to use:
    Code:
    OWOUT DataPin,1,[MatchRom,  OW_Loop_VAR  , ConvertV]
    
        OW_Loop_var   VAR   BYTE [8]
        OWbuffer1    VAR  BYTE[8]   ;SN first sensor
        OWbuffer1[0]= $26  
        OWbuffer1[1]= $7A
        OWbuffer1[2]= $BA
        OWbuffer1[3]= $11  
        OWbuffer1[4]= $01
        OWbuffer1[5]= $00
        OWbuffer1[6]= $00
        OWbuffer1[7]= $D8
        OWbuffer2    VAR  BYTE[8]   ;SN second sensor
        OWbuffer2[0]= $26  
        OWbuffer2[1]= $A7
        OWbuffer2[2]= $AB
        OWbuffer2[3]= $11
        OWbuffer2[4]= $10
        OWbuffer2[5]= $00
        OWbuffer2[6]= $00
        OWbuffer2[7]= $E8  
     
    OW_Loop_var = OWbuffer1
    GOSUB  OWroutine
    OW_Loop_var = OWbuffer2
    GOSUB  OWroutine
    
    OWrutine:
    OWOUT DataPin,1,[MatchRom,  OW_Loop_var , ConvertV]
    
    It seems to me this would work.  As a test I tried:
    
    OWOUT DataPin,1,[MatchRom, OWbuffer1, ConvertV]
    But it doesn’t work and I can’t seem to figure out how to make this happen. I’ve been reading posts on strings, arrays, EXT, and everything else I could find but I’ve seen nothing that resembles what I’m trying to do. Assistance please.
