your last prog works fine  :U about the error I received this message
write fault error writing device AUX
abort, retry, fail?

[dedndave]

the AUX device is an alias for the COM1 serial port
you must have the debugger switched in or something
some debuggers may use the AUX device for output
that is a no-no on win2000 or higher OS's without ring 0 privileges
maybe it is a setting in the debugger - not sure

I am using MASM 16bits under windows xp sp3 and cpu intel E8400.

[dedndave]

well - something is trying to send output to the COM port
