Open the file both ways. Then you can do a READ REC FROM FILEHANDLE, ID ELSE WRITE "" ON FILEHANDLE, ID END OPENSEQ..........

That's how I usually do it. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Chauhan, Savita Sent: Monday, September 20, 2004 1:44 PM To: [EMAIL PROTECTED] Subject: [U2][UD] Create file/record if it does not exist Hi, Is there a UniBasic command which will let me do the following: ------ Open a seq file. If it does not exist then create one and open it. ------- The seq file that I want to create/open is in the _HOLD_ directory, so its kinda record in the _HOLD_ file. I thot of working with the STATUS code returned by OPENSEQ. But, it returns a 0 if the record does not exist and the same 0 if it's a successful open!! How do I check the existence of this record/file? Thanks. ------- u2-users mailing list [EMAIL PROTECTED] To unsubscribe please visit http://listserver.u2ug.org/ ------- u2-users mailing list [EMAIL PROTECTED] To unsubscribe please visit http://listserver.u2ug.org/ ------- u2-users mailing list [EMAIL PROTECTED] To unsubscribe please visit http://listserver.u2ug.org/ ------- u2-users mailing list [EMAIL PROTECTED] To unsubscribe please visit http://listserver.u2ug.org/
