BASIC Computer Games, Super Star Trek, page 159, line 530:

530 FORI=1TO9:C(I,1)=0:C(I,2)=0:NEXTI

Super Star Trek is one of the best test codes you can find, it has an example 
of practically every construct in "standard" BASIC, with the exception of "GO 
TO" as opposed to "GOTO", which some considered to be a separate token (likely 
those from houses with prior JOSS/FOCAL experience).
