When I was in the 4th or 5th year of high school (so 17-18), a
schoolmate brought in a brand new pocket
https://en.wikipedia.org/wiki/HP-35 which his father (a scientific
journalist) had in vision, and we played with it for a while (he did
not buy it after all).

I started programming (Fortran of course) on the University Univac 1108
during the 2nd year of university. Among my first (user-chosen)
programs there were: a program to print the decimal values of all
characters (Univac had 36-bit word of 6 6-bit bytes); a program to
compute with full precision (using an heuristic algorithm) Sissa's
problem https://en.wikipedia.org/wiki/Wheat_and_chessboard_problem (was
beyond the precision of 36-bit integers); a finite-difference solution
of the two body problem (on the first run Earth leaped away on a
straight line because of an incorrect implicit variable typing) :-)

In high school, we had access to an IBM 370 running Call/OS,
and Teletype ASR33 terminals.

I wanted to find the EBCDIC to ASCII conversion table, so wrote
a Fortran program to print out all 256 characters, with
a loop and A1 format.

Partway through running it, the system crashed.
Oh well, try again the next day.

Partway thought running it, the system crashed.
I didn't try running it again. It seems that there is a
character that crashes the system when printed.

So, the opposite of your program.
