CompuServe Messages

Hi, I'm a (very) new Amiga user running an A-2000. As an experienced MS-DOS user, I have long been a CompuServe afficionado. My modem and communications software is all on my MS-DOS machine, however. I have discovered (obviously) that I can still talk Amiga on CIS, but wonder about downloading Amiga public domain files. If I use an MS-DOS machine to download an Amiga utility from CIS – how can I get it to run on my Amiga. Assume that my MS-DOS 3.5 inch floppy (to which I will copy the Amiga utility) will be unrecognizable by the A-2000. (I obviously am resisting the idea of buying an Amiga modem and Amiga communications software, since I already have both running on my MS-DOS machine.) Is there an easy way to get the A-2000 to recognize files from an MS-DOS machine? Any replies will be greatly appreciated. Thanks, John
