Abstract
Abstract A method and apparatus for debugging a hierarchically structure page description language document. As a hierarchically structured page description language is being processed, a picture/pageset stack is used to keep track of the different hierarchical levels of the document. A prologue data structure is used to keep track of various system parameters at each hierarchical level and a current context of interpretation data structure is used to keep track of system parameters as a content portion of the document is being processed. During the debugging operations, system function debugging commands can be entered which pertain to setting and deleting break points and processing of the document by the system and debugger. There are also display function debugging commands which allow a user to display any of the system parameters using the system information stored in the data structures used by the system.
