Maybe that was it... MS BASIC on a C= PET, with subroutine calls and
FOR/NEXT nested deep enough that one _could_ see the bottom.  I never
did a GOSUB-only test, but ISTR having to design some stuff with stack
depth in mind (I did a lot of stuff with Interactive Fiction/Adventure
Games in the late 1970s in BASIC, then I learned 6502 assembly ;-)
