Re: [U2] Sequential Files Question
Al, Do the following: OPENSEQ FNAME TO OUTFILE ELSE NULL WEOFSEQ OUTFILE ON ERROR STOPM 'FATAL ERROR: - Cannot write to file ':FNAME Now, you should be able to perform the writes without a problem. By the way, the ON ERROR clause is optional. The WEOFSEQ will either create the file, or write an end of file mark at the end of an existing file, making the file null. If you want to keep the data, if the file exists, then add the WEOFSEQ in an OPENSEQ ELSE condition... but you need to position the pointer to the end of the file or you will be stepping on existing data.

If you had the proper permissions you would have had a buddy.txt file with: ECHO is on. in the file. The '' redirects the output to the file indicated (creates it if it doesn't exist or overwrites it if it does). I use it to create a log from a batch file: Date /t batchfile.log Time /t batchfile.log The '' will append the output to the file.

Re: [U2] Sequential Files Question
An interesting point about Windows 2008 R2 (it's only 64 bit) is the replacement backup utility cannot both save from a particular drive and store the backup to the same drive. So, if I were crazy enough to build a server with just a C: drive I would have to set the target for the backup file to a network share, as I can't store it on the C: drive (because I'm saving data from the C: drive. This pretty much indicates that one needs at least three drives for a Windows Server; one for the O/S, one for the backup file, and one to store all the data that needs saving. There didn't seem to be too much difference in backup speed using a network share as a target vs a local share, but one would think there would. Go figure...

[U2] Sequential Files Question
Unidata 7.1.20 I've never dealt with sequential files, but I have a need to output records to a text file. 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. Al DeWitt ___ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users
Re: [U2] Sequential Files Question
Here's a wrapper I've used around seq file opens for years on unidata. F.FILE IS THE RETURNED FILE HANDLE-all others arguments are inputs. You need not force creation (at least not on *nix) http://jeff.hampshire.edu/seq.txt Jeff Butera Sent from my iPhone On Sep 8, 2010, at 6:55 PM, Al DeWitt adew...@stylmark.com wrote: Unidata 7.1.20 I've never dealt with sequential files, but I have a need to output records to a text file.

I forgot to mention that I'm on Windows. My output path is: C:\OUTPUT\ My file name isAPCHECKS where is a counter that gets incremented each time the program is run.

Re: [U2] Sequential Files Question
Interesting that the code was sent through malformed like that, but that's a different issue... Just before the offending stop, add CRT STATUS() This will return the reason it is dropping into the ON ERROR section. Value - Description --- 0 - The record does not exist. 1 - The file you specify is not a sequential-access file. 2 - The file does not exist. 3 - The READONLY clause was included in the command statement and the record does not exist. 4 - An unknown error occurred (such as having too many files open or permission problems). -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 12:15 PM To: U2 Users List Subject: Re: [U2] Sequential Files Question I GET THE FOLLOWING MESSAGE [FATAL ERROR: - Cannot open file C:\OUTPUT\APCHECKS1002] and I'm sent to the colon prompt.

Re: [U2] Sequential Files Question
Al; I use the following code: OPENSEQ 'OUTPUT.FILE', 'APCHECKS' TO OUTFILE THEN CRT 'APCHECKS ALREADY EXISTS' STOP END * code to build each line goes here MORE.DATA = 1 LOOP WHILE MORE.DATA DO LINE = 'data' 'L#9':MORE.DATA 'L#25':'still more data' 'L#20' WRITESEQ LINE APPEND ON OUTFILE ELSE CRT 'NOT AT END OF APCHECKS' MORE.DATA += 1 IF MORE.DATA = 25 THEN MORE.DATA = 0 REPEAT CLOSESEQ OUTFILE Where OUTPUT.FILE is a VOC item (which means I can change the location of the file without recompiling/changing code): DIR C:\OUTPUT D_VOC Using the THEN construct means the program will stop if that item already exists so you won't overwrite any existing data. Technically, the file won't actually exist until you do the WRITESEQ, but it won't matter that it won't already exist, it will create it. You can't really deal with OUTFILE as a variable - it's really a (type of) file handle. The WRITESEQ will fly through the file - you don't have to worry about creating a large array - it will just keep writing until it hits the limit (not sure if it's the OS limit or UniData's 2GB limit).
