Lpc2000

Hi Tom,

thank you for your help. The result is still not my problem. I changed
that sometimes from reslut[1] to result[0].

The problem is, the programm sticks at the call of the IAS-routine.

Any idea??

Best regards  Cris

return result[1] instead of result[0]. results[0] only says the
cammand is sucess.
