Hello John,

Using the TASKING assembler on the following code:

ORG 00h
ljmp main
ORG 03h
ljmp isr_X0
ORG 0Bh
ljmp isr_T0
ORG 064h
main: jmp main

isr_X0: reti
isr_T0: reti
END


resulted in the following list-file:

8051 assembler v5.0 r2 SN00089340-049 (c) 2000 TASKING, Inc.

4 ORG 03h
0003: 020066 5 ljmp isr_X0
6 ORG 0Bh

8 ORG 064h

0066: 32 11 isr_X0: reti
0067: 32 12 isr_T0: reti
0068: 13 END


and this HEX file:

:060000000200640200662C
:03000B0002006789
:0400640080FE3232B6
:0400000300000000F9
:00000001FF

Looks OK to me..
