[GAP Forum] Binary code generating function

[tendai shumba]

Dear Forum
I am trying to generate binary codes  given a basis. I found : 
CodeGenBy:=function(codebasis)
return Subspace(GF(2)^Length(codebasis[1]),codebasis) works but it done not work 
for the empty basis codebasis:=[];
How can I make this to work?
