ABSTRACT:
A method and apparatus for checking for portions of record variables that are referenced before they are assigned a value. This checking occurs in the semantic checking portion of a compiler for a high level computer language. The present invention creates certain entries in a name list table (the symbol table) that point to two additional lists: the flist (fields list) and the clist (component list). The semantic analyzer refers to the name list table and to the clists and flists to determine whether a portion of a record variable has been assigned a value. If no value has been assigned to the portion of the record variable, the compiler prints an error message.
