Drawing a box

[Brian K. White]

There are 3 characters in the repeat string.
150 is divisible by 3.
125 is not.

Repeat 125 produces 41 copies of "\g0" and then 2 characters "\g"
You are then appending "\g9" to that, resulting in "\g\g9"

Apparently fp is reading a character after the \g and not noticing that 
the particular character was a backslash.
Instead of abandoning the attempt to parse the previous backslash code 
and starting over with the new backslash,
It's reading "\g\" and since there is no "g\" character it outputs "?" , 
then, since the \ from \g9 was "eaten" by the previous backslash code, 
the remaining "g9" is just plain text and is output as such.
