Oh.. you should not put me into reminiscence mode 
Nowhere as old but I still have my M$ QuickBasic disks, although the manual (450 pages) got a bit water damaged one time.
Happy DOS days, there was a shareware version of M$basic (edit called GWbasic - apparently from gee-whiz-basic) called pradoBasic, described as almost as good as M$ - with a splash If you find useful please send 5$ to xxxxx As-good-as because it was M$Basic, One binary file, easily editable to add the message...Scammers, not much changes does it.
