You can't do stuff like that on a PC or a Mac, ...

The last time I laid one out, I did it in Word (and I bet you can't do it that way(?))

But I've also done that, and some slightly more tricky stuff, in BASIC back when the PC I could get at the office only had a 1D 5.25 Floppy to work with. The tough part was getting the program that your buddy was trying to run in PC-BASIC to run on the machine you had that had GW-BASIC. And "breaking the encryption" when some idiot "did you a favor" but used the default save on the program you'd been building for a week or two.
