In SX/B version 1.51.03 if you attempt to use a WORD variable as an array index you should get an error message (usually incorrect number of parameters). But the SEROUT command does not issue an error. In fact it will send the address of the array instead.
 



[code]
DEVICE SX28, OSCXT1, TURBO, STACKX, OPTIONX, BOR26
FREQ 4_000_000
 
sendStr  VAR BYTE(11)
temp     VAR WORD 

  

PROGRAM Start NOSTARTUP
 
Start:
  PUT sendStr, "HELLO THERE"
  FOR temp = 0 TO 10
    SEROUT RA.0,T9600,sendStr(temp) ' DO NOT USE A WORD AS AN ARRAY INDEX
  NEXT
END
 

The "fix" is to just use the LSB of the word variable.
