Dear Forum,

I just tried to create a matrix containing only zeroes.
(and have done it with NullMat(m,n))

But before I looked into the manual I tried it with ``ZeroMatrix''
and the prompt-line-completion-feature (pressing TAB):

gap> ZeroMa # pressed TAB
ZeroMapping
ZeroMatrix
gap> ZeroMatrix;
Variable: 'ZeroMatrix' must have a value
gap> NullMa # pressed TAB
NullMapMatrix
NullMat
NullMatrix
gap> NullMatrix;
Variable: 'NullMatrix' must have a value
gap> NullMat;
function( ) ... end
gap>

If ZeroMatrix and NullMatrix do not exist, why they are offered by the
``TAB-feature''

BTW, Im using
GAP4, Version: 4r2 fix4 of 19-July-2000, i586-pc-linux-gnu-gcc

c ya
        Sergei
