    From DesotoFireflite@VERT/VALHALLA to All on Mon Mar 7 08:41:36 2022
    I want to be able to add to the top of a file, but I can only find out how to add to the bottom of a file. Currently I am using:

    fopen file 0_CREAT|0_WRONLY|O_APPEND "C:\SBBS\XTRN\INFO\INFO.LST"

    and that appends to the bottom of the list, but I want to show the newest to oldest, not oldest to newest.

    I'm assuming I just leave off the O_APPEND, but is there a correct way.

    Thanks

    i probably could have done this like 15 or more years ago with baja, but I can't process the way to do it now.

    what i would do (which requires no brain power) is to cat your new line to a new file, then cat your current list to that file, then move that file over your info.lst

    or if your list file has a date or something sortable, you could just sort the file.

    Leaving off O_APPEND will *overwrite* the portions of the file you write to. There is no standard method for "inserting" data into a file. You would have to read the file contents and re-write them with the "inserted" data first, then the old data.

    I hear you, at 70, I'm loosing a lot of my skill set also. <BFG>

    or if your list file has a date or something sortable, you could just sort the file.

    Both good ideas, but I like the sort issue best. I may be able to pull that off, but I will have to look at the file first.

    Thanks

    What are you trying to achieve? If part of the file changes, could you
    use an include to read in the bit that changes, and then just write
    your included file?

    It's just a graffiti wall I'm working on, but I wrote it to put the new info at the bottom, but now I've changed my mind and wan't the newest additions at the top. Thanks for the suggestion. I'm gonna play with it in a few days as soon as time let's me. I got side tracked working on another project. Again, Thanks

    Use the tac command :)

    $ echo "feck
    drink
    girls
    arse"|tac
    arse
    girls
    drink
    feck


    Seriously, a couple of ways to do it but you can probably modify the
    answer given to this question easily enough.
