[texhax] unexplained space

Some of my macros yield unexpected space to the left and/or
right of what is the expected return.
Eliminating this space is my problem. I don't know what
loops, conditionals, techniques like that used in the length
macro, p219 of the TeXbook.
I can see no pattern to the amount of such space but the
amount is usually reduced
by tightening up on the code, by that I mean removing gaps
between statements of the code
(gaps that for most macros I would leave just to maintain
This tightening reduces the code to one long line, gaps
only at points where, well, without them there
is no output or the output is incorrect. One example of
such a necessary gap is between
the definition of a count register and an \if. Like I
said, tightening helps but it does not eliminate all the
I wonder if anyone out there has had experience with
this problem; if so I would be very grateful
for a hint on how to deal with it. In any case, thanks
very much and have a great day.
