Another small point. The end of the code should have a truncate in it: 

...
print ON $ordernum;
truncate ON, tell;
close(ON);

Not needed in this case, but a good practice to get into, just in case the new text is shorter in length than the previous text. For the record, I agree with the "don't use unlock" crowd - let close take care of it.
