Abstract
A scattered context grammar, G, erases nonterminals in a k-limited way, where k is a positive integer, if for every sentence belonging to G's language, there is a derivation such that in every sentential form, between every two symbols from which G derives non-empty strings, there is a string of no more than k nonterminals from which G derives empty words. This paper demonstrates that any scattered context grammar that erases nonterminals in this way can be converted to an equivalent scattered context grammar without any erasing productions while in general, this conversion is impossible.
