I've usually only used it where I expect one user to be accessing the file at a time anyway. However, it should (mine does on UD 7.1.6) compile. You are using an "END" before the next THEN or ELSE - that might do it.
hth Colin Alfke Calgary, Canada -----Original Message----- From: Al DeWitt Unidata 7.1.20 ECLTYPE P Whenever I try to include the LOCKED option in the OPENSEQ statement my test program does not compile. If I leave it out it does compile. When two users run this program one executes the OPENSEQ command and the other appears hung...no message, nothing. When the first user closes the file the second user continues on. Since LOCKED appeared to allow me to tell the other users that the file is locked and not to give up hope what do you folks do to get around this dilemma? Thanks.
