Create empty registry value?

[Charles Dye]

Does anybody have a clever way to create an empty registry entry of type REG_SZ using 4NT/TCC? @REGSET deletes any matching entry if it's passed a blank value (as documented.) I thought it would be possible to pass a value of ``, but that creates a value with two backticks (why?) Variables or functions which evaluate to an empty string also delete the registry entry. A string consisting of all spaces, e.g. %@CHAR[32], also deletes the entry.

Of course I could call REGEDIT.EXE or REG.EXE, but that's inelegant....

Why is it inelegant? REG and RegEdit exist on all PC's since Win2K.

Oh, mostly just because I prefer to use internals wherever possible.

That won't be empty; it'll have one character in it.

Visibly empty but with one character yes.
