I wrote one in rexx that runs under TSO on an IBM mainframe if that's of any use. It scrolls and displays any year/day or whatever you want it to. Does other bits and bobs like issuing reminders and so on.
Do you have an IBM mainframe?
Exactly, but one has to ask.
Yes, but not one of those new-fangled modern machines running TSO. :(
*swallows*
*brings peace*
Oh God.
Stuck with that image all day now.
