Dusty, when you record your band, you "lay down tracks". This is a universal recording studio colloqial expression also known as "tracking".
From your follow up it sounds like you just let the "tape roll" from the start of practice until the end, and you have multiple songs in one long contiguous file that you want to break up into individual song files.
If that's the case, in general you have two options:
(a)Export that one long file into a DAW and use the DAW to break it into the individual songs;
(b)Use the 2488 to "Master" each song individually, move the individual master over to a computer, and repeat until done.
Once you have the individual song files, you could "burn" them to a standard audio CD, which creates standard "audio tracks" to play back on a standard CD player; or burn them to a CD as individual computer data files.
I work with a DP-24, and I'm not familiar with the older 2488. Option "b" is how I would do it on the DP-24. Perhaps someone will come along with more specific suggestions.
If you've misplaced your 2488 manual, it's available for free download on the TASCAM web site as an Acrobat PDF file. The manual should have a section on the mastering process.
