Word description Deploy flag. If set, the deploy tool retains word properties containing metadata for C types and struct classes; otherwise, these properties are stripped out, saving space.
Off by default.
The optimizing compiler is able to fold away calls to various words which take a C type as an input if the C type is a literal string, for example,
If your program looks up C types dynamically or from words which do not have a stack effect, you must enable this flag, because in these situations the C type lookup code is not folded away and the word properties must be consulted at runtime.
