Hi everyone-

I'm working on some parsing routines in SX/B and have run into a problem that I've been pulling my hair out for most of the day. This is my first experience programming with SX/B and I've been making some pretty good progress until this issue. I'm using SX-Key v3.10 and SXB 1.42.01.

Here is the relevant, problematic code:
[code]
rcvBuf		VAR	Byte(8)
tmpWord		VAR	Byte(2)

tmpWord = 0

FOR idx1 = 0 TO 6
  IF rcvBuf(idx1) <> "." THEN
    rcvBuf(idx1) = rcvBuf(idx1) - "0"
    tmpWord = tmpWord * 10
    tmpWord = tmpWord + rcvBuf(idx1)
  ENDIF
NEXT
[/code]

The code should take a string like "00033.4" and convert it to two bytes: $014E (which is 334 in decimal). I'm getting the following error:

Error 16, Pass 1, UNKNOWN COMMAND: "LET"

If I change tmpWord to a single Byte, the program will compile fine, but will overflow the variable for any string longer than "00025.5". Is SXB not designed to handle words (16-bit) variables or am I just doing something else wrong? Actually, the program SHOULD be using three bytes to handle any string up to "99999.9", but I'm having enough trouble with 2 bytes at the moment.  

Any help would be appreciated! :)

Joe
