You can attempt to open the table exclusively (use mytable exclusive) and trap for the error 'File in use by another' if someone else the table open. If youi get the error, you can then use the NOUPDATE keyword in the use command.

local llerror, lcerror
lcerror = on('error')
llerror = .F.
on error llerror = .T.
use mytable exclusive
on error &lcerror
if llerror then
   * couldn't open table exclusively
   use mytable shared noupdate
endif
