My first computer I could swear I’ve written about this before, but I can’t find it, so it must’ve never escaped Twitter

There were clearly several different authors here! Programs 6 and 9 are the only ones to start numbering from 100, to have 999 END as their last line, to ask if the player wants to play again, and to only accept YES as an affirmative answer. 3 and 4 are the only two to use the SOUND statement, and both omit the space between the word SOUND and its first argument. 1 and 8 are the only programs to finish with an END that doesn’t use 999 as its line number.

• The PRINT statement accepted multiple arguments, separated by either semicolons or commas, though the manual doesn’t explain the difference (if any). Program 1 stands out as the only program to manually insert a space at the end of a literal string followed by a variable. The tutorial part of the manual implies that PRINT inserted spaces between its arguments automatically, which makes me wonder why this one program felt the need to add its own. Program 8, seemingly by the same author, never prints two things on the same line.
