I think this is what you intended for me to do.. I'm not sure how to advance the array location in the loop. You will see my comment in the code. Thank you again for the help!
Code:
 usbservice
doloop:
       inbyte = 1
       USBin 3, action, inbyte, doloop2        ' Get a char from usb port
verify:
       IF action = 102 THEN   ' Verify connection
       USBout 3, action, 1, verify
       ENDIF    ' end of verify action
     '  IF action = 117 THEN  ' Write EEPROM
     '  USBOUT 3, action, 1, doloop2
     '  tempval = 0
tlabel2:
     '  USBin 3, char, inbyte, tlabel2
     '  WRITE tempval, char
     '  USBout 3, char, 1, startloop
      ' tempval = tempval + 1
      ' IF tempval < 255 THEN tlabel2
     '  ENDIF ' end of Write action
valuesout:
       IF action = 99 THEN    ' Return last input and output
       USBout 3, mafout, 6, valuesout
       ENDIF ' end of IO action
       IF action = 107 THEN   ' Dump EEPROM
       tempval = 0
Dumploop:
       Read tempval, epromdump[0]  'epromdump is a 256 byte array
        tempval = tempval + 1 'advance to the next eeprom location 
        'not sure how to advance places in the array for the new eeprom value
        USBout 3, epromdump, 256, dumploop
