The easiest is to create and set a private variable (say to 0) just before you open the file, let your error handler set the variable (say to 1) if it exists (use TYPE()) and test the variable after the opening sequence. If it is still 0, then you opened your file exclusively, otherwise, the opening instruction failed for one or another reason. Do not forget to RELEASE the variable if you do not need it anymore.
