There are basically 2 ways :
1) Using error

local llInUSe
on error llInUSe = .t.
use Table1 exclusive
on error
if llInUse
*...

2) Try to open lowlevel readwrite

local llInUse
lnHandle = fopen('table1.dbf',12)
llInUse = ( lnHandle < 0 and ferror() = 5 )
if lnHandle > 0
 fclose(lnHandle)
 use Table1 exclusive
endif
