Hi,
sorry, but with a bit cleaner definition like
SetAttributes[{DefinitionString}, {HoldAll}]
DefinitionString[expr_] :=
ToString[Unevaluated[expr]] <> " = " <> ToString[expr, InputForm] <>
";\n"
and
b=6;
stream = OpenWrite["tmp.txt"];
WriteString[stream, DefinitionString[b]];
Close[stream];
I can't reproduce your problem. And
Put[Definition[b], "tmp.m"]
may do almost the same.
Regards
Jens
