Include "modedefs.bas"  ' Include serial modes

TX Var GPIO.1           ' Define serial out pin
RX Var GPIO.2           ' Define serial in pin
B0 Var byte

   ANSEL = 0            ' Set all digital

   If (B0 < "a") or (B0 > "z") Then print ' If lower case, convert to upper
   B0 = B0 - $20

print:
