DOS utility to display 1st line of all files in directory? (Users)

Thanks Rugxulo!

I'm going to take your batch file (see below) for a spin. Years ago I used to write a lot of batch files and had a heck of a lot of fun doing it. But that was a decade or more ago, so I'm rusty now. But your little batch file will give me something to play with and try to get back up to speed.

I don't have QBasic installed on my computer, so I figure I'll have to try to find it on an old floppy and install it before your file will work; right? (What do I need to do besides copying the QBasic files to a directory and adding the directory to my path?).

I'm only able to work a few minutes a day at my computers, so this may take me a day or two to get set up.

In the meantime, will your batch file look at the first line of all files in a directory, not just the ones with .txt extension? I use an alpha/numeric code for the three character file extensions as a way of tagging files.

Also, could I add a routine to your batch file so that it would sort the first lines into alpha/numeric order?
