defined:core_misc — immediate primitive
Search the dictionary for _name_. If _name_ is found, return TRUE; otherwise return FALSE. Immediate for use in definitions.
This word will actually return what FIND returns (the NFA). does check for the word using find (so it does not throw like ' ) and puts it on stack. As it is immediate it does work in compile-mode too, so it places its argument in the cs-stack then. This is most useful with a directly following [IF] clause, so that sth. like an [IFDEF] word can be simulated through [DEFINED] word [IF]
