Abstract: A process for automatically generating declaration statements from the external definitions (I, II) of a source file (12). The process identifies the data-type identifiers of an external declaration (I, II, IV, V), converts user-selected data-type identifiers into data-type keywords, and stores them in a first memory location (38, 50). Object declarators of the external declaration are also identified and stored in a second memory location (49, 50). External declarations that are external definitions are identified and a declaration statement for each external definition is written to an EXTERN or STATIC include file using the stored data-type identifiers and object declarators. External declarations that are typedef declarations are identified and an entry is generated in a symbol table for converting user-selected data-type identifiers to data-type keywords.
