on Windows 9x/ME, you cannot scroll in an MS-DOS Window
now you're gonna ask: "how do i scroll through the list then ?" so i'll answer it immediately
one way to do this, is to save the screen output to a file.
if your commandline is:
i6comp l data1.cab *.*
then type instead:
i6comp l data1.cab *.* > list.txt
this will create a file list.txt containing the garbage you would see on your screen
