PrintTo(<stream>,<object>) and AppendTo behave like Print and therefore break the lines
as though writing to screen (see Section 10.4 of the manual). In preference one uses
WriteAll(<stream>, <string>) which simply writes the string to the
stream byte-by-byte.

I believe the following does what you want.

gap> n; # n is an integer

Hope that helps,
