Addition problem with word value on PIC18F8722

[ImAnEE]

Having a strange problem with addition to a word. I'm outputting the number to the PIC18F8722 EUSART. I'm using PBP v2.60. I can output a constant, e.g. 31416, but if I add one to a word value starting at zero, I get some weird results.

Here's a snippet from my code:

IF (bXMIT_CNTR >= 20) THEN
CONV_X = CONV_X + 1
'CONV_X = 31416
bXMIT_CNTR = 0
SERIAL_MSG_FLAG = 1
ENDIF


And here are some of the results. I would expect 1, 2, 3...:
11111
22222
33333
44444
55555
66666
77777
88888
99999
11110
11111
11112
11113
11114
11115
11116
11117
11118
11119
22220
22221
22222
22223

Any ideas?

Thanks!

My mistake. The problem is not with the addition, but rather with my binary to BCD conversion routine that I'm using to output the number serially. I foolishly tested it only with 5-digit numbers, not smaller ones. It works great with the 5-digit number. Sorry about that.
