Rather than store the files under individual file names, could you store them as different file members within the same file? Then, in i5/OS, you could just specify to read all members when processing the data at the end of the day.

List, Here's another unusual process we have on our VSE mainframe that will have to be duplicated on the iSeries. I am hopeful that the iSeries can handle this in a much easier manner than does VSE, but I am too new to the environment to know. Here's the process on VSE.... During the day, depending on which customers' data has arrived, it is processed and their data "staged" to a sequential file in a specific VSAM catalog. Throughout the day, more data files are generated. When it is time to begin the nightly run, we have to "gather" these files together (merge to a single dataset) and then purge the original individual files. (the catalog is backed up before the process begins) The way this process is currently handled is a COBOL program reads the VSAM catalog, looking for datasets whose name matches specific templates. This program generates JCL for a second job where another COBOL program will process each of the specific files passed in the list that the first program prepares. There is only one input file defined in this program. Before each input file open, an assembler routine is called which overrides the "ASSIGN TO name" of the file hardcoded in the ASSIGN clause of the program with one that is passed to the program in the list. This way it opens and processes each file dynamically according to the list for that day. If the iSeries provides a way to concatenate files of a similar format with names that match certain template(s) to a single file, this will be a piece of cake. The constraints here are: 1) there will be one-to-many of these files for any given run - but all in the same library 2) the files will be identified by one of several "strings" in their physical names 3) it is possible there could be other files in the same library but are irrelevant to this process (so #2 is very important) How best to accomplish this on the iSeries? -- Regards, Michael Rosinger Systems Programmer / DBA Computer Credit, Inc. 640 West Fourth Street Winston-Salem, NC 27101 336-761-1524 m rosinger at cciws dot com -- This is the Midrange Systems Technical Discussion (MIDRANGE-L) mailing list To post a message email: MIDRANGE-L@xxxxxxxxxxxx To subscribe, unsubscribe, or change list options, visit: http://lists.midrange.com/mailman/listinfo/midrange-l or email: MIDRANGE-L-request@xxxxxxxxxxxx Before posting, please take a moment to review the archives at http://archive.midrange.com/midrange-l.
