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.

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 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.

Ok, Thanks, that was what I was afraid off... Looks like I have some
work to do. <BFG>

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
