Trapping error 426

[Harry Binswanger hb@xxxxxxxx]

My program calls a file and sometimes it's already open. That gives me
error 426 and puts up the message that the file is already open, do I want
to go to it, or . . .
When running this program, I always want to go to it. How do I prevent it
from putting up the message and waiting for my response? Is there a way to
check if a file is open, because if so, I could simple issue gofile when
that check indicated it's already open.

Thanks,
Harry
