RE: [U2] Clearing a Sequential File:
From the 8.3.3 paper manual (holy object here) - i found this snippet : OPENSEQ 'FILE.E','RECORD4' TO FILE ELSE CREATE FILE ELSE ABORT WEOFSEQ FILE WRITESEQ 'HELLO, UNIVERSE' TO FILE ELSE STOP nothing beats a printed manual :-)) - i hate those freak pdf monsters!

Re: [U2] Clearing a Sequential File
A sequential file within the program bycan by truncating the file before writing to it. This is accomplished by using the WEOFSEQ filevariable statement after the OPENSEQ and before the first WRITESEQ. Hope that helps! -- James --- u2-users mailing list [EMAIL PROTECTED] To unsubscribe please visit http://listserver.u2ug.org/
RE: [U2] Clearing a Sequential File:
There are a number of approaches to this. If you're on a *nix platform, you could rm and touch the file you want and that'll create the null file. On Windows you can do a similar thing, but of course the OS verbs are different. I use a cross-platform approach that doesn't use OS verbs at all. First, open the directory file as a regular file. Use DELETE to remove the old item. Then, when writing to the file, on the first output just WRITE it to the DIR file under the sequential name. Then open the sequential item and WRITESEQ to it thereafter. This is a bit more complicated than other approaches, but if you WRITE '' ON dirfile,name at the start (which is the most common variant of the technique) you'll get a blank first line. If you don't mind that blank first line, then that may be an easier way to go. -Kevin [EMAIL PROTECTED] http://www.PrecisOnline.com -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ron Moore Sent: Tuesday, August 24, 2004 11:41 AM To: [EMAIL PROTECTED] Subject: [U2] Clearing a Sequential File: I am able to OPENSEQ and WRITESEQ for a sequential file, and need to clear the records or data before writing to this file.

RE: [U2] Clearing a Sequential File:
If you do a WEOFSEQ after all your WRITESEQs, the file will be truncated at that point. Something like this: OPENSEQ 'path/filename' TO F.SEQ ... * pointer is at beginning of file LOOP WHILE STUFF.TO.WRITE DO WRITESEQ STUFF.TO.WRITE ON F.SEQ ELSE ... REPEAT WEOFSEQ F.SEQ ... This insures that even if what you're writing this time is fewer 'lines' than last time, the file will not contain any leftovers at the end. Richard B.

RE: [U2] Clearing a Sequential File:
Sequential and dynamic access are defined by the way the file is opened. So you can always do a : EXECUTE 'CLEAR-FILE GODZILLA' before opening the file and it will be clear.

RE: [U2] Clearing a Sequential File:
I tested the WEOFSEQ on UD6 and it works real well, but I seem to remember on earlier versions of Unidata you had to have the record there before you could OPENSEQ. Or perhaps this was UV? I just tested this and on my UD6 you can OPENSEQ a non-existant item and it creates the new record, so you wouldn't have to go through all these hoops if you're UD6. -Kevin [EMAIL PROTECTED] http://www.PrecisOnline.com -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ron Moore Sent: Tuesday, August 24, 2004 1:31 PM To: [EMAIL PROTECTED] Subject: RE: [U2] Clearing a Sequential File: Thanks for the idea, Kevin.
