STATE VARIABLE MANAGING DEVICE AND HIERARCHICALLY STRUCTURED DOCUMENT PROCESSOR

摘要

PURPOSE:To provide an efficient processing means for a hierarchically structured page description language such as an SPDL and a managing means for a state variable. CONSTITUTION:Each structure level of a document generates prologue data structure 220 for managing a system parameter. While the content part (token sequence element) of the document is processed, current analysis context (CCI) data structure 240 is generated and this data structure is used for storing the parameter of a system as well. When processing and printing only one part of the document and performing the other presentation, all the parts preceding to the relevant required part of the document is not required to be processed. Both the prologue data structure 220 and the CCI data structure 240 store pointers 229 and 248 indicating a state variable table storing the value of the state variable.
