More visually pleasing, and several keystrokes shorter, for rapid input on an unattended store demo machine: 10 print "poop ";:run FWIW, the very first version of BASIC in 1964 supported FOR (https://en.wikipedia.org/wiki/Dartmouth_BASIC#First_Edition https://en.wikipedia.org/wiki/Dartmouth_BASIC#First_Edition). I never used DOS machines but https://gunkies.org/wiki/Microsoft_BASIC https://gunkies.org/wiki/Microsoft_BASIC claims that BASICA was based on Microsoft's BASIC, and that definitely had FOR. Young you must have arrived at the concept of a for loop without knowing there was a keyword in the language designed to support that, which is pretty cool!
