Assuming you know what you are doing (replacing some functions can lead to
weird errors),
MakeReadWriteGlobal("TheFunction");
(note: String, not variable!) will remove write protection from
TheFunction
and allow you to overwrite it.
MakeReadOnlyGlobal is the inverse operation.
If the issue is simply with reading in a file, using
Reread
instead of
Read
will allow a second call to `InstallGlobalFunction' to overwrite the first
instance.
Best wishes,
