// Please be more specific (if you can) when exchanging information
// on the "KCl i/o" problem. I never encountered what you describe.
// It probably works on certain OSs (System V) and not on others, it
// is function of your terminal i/o mode, stty... You can't generalize
// the effect of read-line from one system to another unless it is fixed
// or (does not work anywhere).
There's far too much pointless discussion on this subject already,
but I will explain again.
When the KCL toplevel reads an s-expression, it leaves the final
newline unread if the input is a list. With the newline character
still in the input stream, if the first input operation done by
the user program is a read-line, it will encounter a blank line.
This problem is obviously independent of operating system or anything
else not part of KCL.

This does not have the same problem because read, of course,
skips over leading whitespace, which includes newlines. Independent
of that, the read function (as oppose to read-preserving-whitespace)
probably does read a single trailing whitespace after a number.
