If you run this code: OPENSEQ FNAME TO OUTFILE ON ERROR STOP 'FATAL ERROR: - Cannot open file ':FNAME END THEN STOP 'FATAL ERROR: - Already exiting file called: ':FNAME END ELSE CRT "FILE OPEN SUCCEEDED!" WRITESEQ "Dummy data" ON OUTFILE THEN NULL END
What happens? -----Original Message----- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Al DeWitt Sent: Thursday, September 09, 2010 10:03 AM To: U2 Users List Subject: Re: [U2] Sequential Files Question I forgot to mention that I'm on Windows. My output path is: C:\OUTPUT\ My file name isAPCHECKS9999 where is a counter that gets incremented each time the program is run. FNAME would be C:\OUTPUT\APCHECKS9999 so that my statement would read: OPENSEQ FNAME TO OUTFILE... However, since APCHECKS9999 would be unique each time it doesn't exist. BTW when I try to display OUTFILE it gives me an Unitialized Variable, zero assumed error.

Each record will be a series of fixed-length fields. Each file will need to be created at the time of opening. The destination will be a Windows folder on one of our servers. I will be using OPENSEQ to open the file. However, since each file needs to be created at time of opening what do I use to create the file? My reading of OPENSEQ doesn't indicate that it will create it automatically if it doesn't exist. Thanks.
