I actually think BAT files are for DOS.
I thought I recall that picture being of a TI-99/4A. That Cosbycoin screenshot displays an impressive number of colors - I thought the TI-99/4A had a maximum of 16 (either total, or onscreen at a time from a larger palette).
yeah, DOS, OS/2 and Windows all have them though. They are definitely still around in windows 7 even. Think cmd is preferred now though.
