    I use currently UltraEdit Professional Text/HEX Editor version 18.20.0.1021.

    I have a large invoice file I need to split & would appreciate some pointers and ideas please.

    Each invoice follows this structure with the first one/two characters of each line acting as a LINE TYPE. 
    All invoices start with a LINE_TYPE of H1.
    The H lines hold the invoice header information (document_number, name & address).
    The P & L lines (of which there can be any number) hold product detail.

    Code: Select all

    H1TEXTTEXTEXTEXT...............Up to 500 characters - terminated by CRLF
    H2TEXTTEXTEXTEXTETC
    H3TEXTTEXTEXTEXTETC
    H4TEXTTEXTEXTEXTETC
    H5TEXTTEXTEXTEXTETC
    H6TEXTTEXTEXTEXTETC
    H7TEXTTEXTEXTEXTETC
    H8TEXTTEXTEXTEXTETC
    H9TEXTTEXTEXTEXTETC
    P TEXTTEXTEXTEXTETC
    L TEXTTEXTEXTEXTETC
    I would like to split the source in to files that would contain 'x' number of invoices (e.g. 25000).

      This can be done with a script. But I have some questions before I start coding it.
      1. Are there more H1 lines after P and L lines or are all H1 lines at top of the file?
        I think, there are more H1 lines after P and L lines, but this is not really clear for me from the example and its description.
      2. Should the P and L lines between H1 lines and below last H1 line of a block also stored in created files?
      3. What should be the file name of every created file?
        For example the created files could be saved in same directory as active file on starting script and with name of active file with _x appended after file name before file extension with x being fixed a two or a three digit number in range 01 to 99 or 001 to 999.

        Firstly, thank you very much for taking the time to reply and offer assistance.

        I'll do my best to answer your questions.

        Question 1: You are right in that all the lines of each invoice will be grouped together followed by the next invoice and so on (H1, H2....,L,L,P,P,H1, H2....,L,P,P,H1...)

        Question 2: Yes, all lines should be output to the created files in the same order. You will also see in the attachment that there are several additional LINE_TYPES, not just L & P, but really we're only interested in the H1 LINE_TYPE as it will always signal the start of a new invoice. It is possible than an invoice may only consist of a header (lines H1-H9) and that no product lines (L, P, etc.) exist. In this case the invoice should still be counted & any lines found output to the created file.

        Question 3: Something along the lines of DMS_HISTORY_SRC_x.dat would be nice with x being the incremented number. The inclusion of preceding zeros would not be necessary. Whatever is easiest to code will be perfectly fine.

        Thank you again.

          Some additional information:
          • It is required for this script that configuration setting Disable line numbers is not enabled at Advanced - Configuration - Editor Display - Miscellaneous on having followed the recommendations in power tip large file text editor. The script requires that UltraEdit counts the lines which unfortunately results also in updating the line number in status bar during script execution.
          • I tried to write the script for avoiding as much window updates as possible. But UltraEdit is designed as GUI text editor being used by users. For that reason UltraEdit updates the line number information on status bar at bottom of UltraEdit main window while running the script. This makes the script quite slow on doing this file splitting task. It would be much faster to split primary on number of lines instead of number of H1 lines, i.e. select a block from current line downwards to next H1 line after a specified number of lines like 350,000. That would reduce the number of executed finds dramatically and UltraEdit could finish most likely this task in a few seconds.
          • I tested the script with UltraEdit for Windows v18.20.0.1028 first on your small example data with variable nInvoicesPerFile set to 3. Then I selected all, copied and pasted the data several times until the example file had 4,988,880 lines and a file size of 520,975,520 bytes (496.84 MiB). I executed the script with nInvoicesPerFile set to 25000 and it needed 41 minutes to create 14 files, 7 files with 365,628 lines and 38,181,520 bytes, 6 files with 365,622 lines and 38,180,980 bytes and 1 file with 235,752 lines and 24,619,000 bytes. It is most likely better to use PowerShell or Python or any other script interpreter for this task on not using a different method for splitting the file like the one I have suggested in previous point.

            This is great! Thank you! 
            41 minutes is a small price to pay. 
            I look forward to trying it out.
            Many Kind Regards!
