I haven't read the compare() function inside the include file,
but the library.doc states that compare() works on objects.

Objects are EITHER atoms or sequences.

The above forces attempt at sequence comparison.

and above this forces attempt at atom comparison.
The reason I say attempt is because a sequenc can contain
a sequence.

My guess by looking at the code is trying to find or filter in the
printer escape codes.  These codes fall between ASCII values
0 - 31. value 32 is the space character.
to do this he should use the followin if command.

if compare(real[1] , 32) = -1 then

This makes sure that it is an atom and that it is less than 32.
everything less than 32 is the printer codes.
