1. An inverse assembler capable of converting the code associated with a stored program stored in a memory of a user's circuit, the code being generated from a microprocessor disposed in the user's circuit and having instructions and data information, into a corresponding set of mnemonics for interpretation by a user comprising: means for entering conversion information into said inverse assembler, said conversion information being a list of code corresponding to said code associated with said stored program and a list of said mnemonics corresponding thereto; means for receiving said conversion information and for storing said conversion information, said conversion information being stored in said receiving and storing means in the form of a set of decision tree tables, each decision tree table including entries for portions of code and mnemonic information corresponding thereto and being in a format corresponding to the format associated with a set of user documentation describing the characteristics of said microprocessor; means responsive to said code associated with the stored program for distinguishing between said instructions and said data information and for assigning a first identifier to said instructions and a second identifier to said data information; means for acquiring and storing said code associated with said stored program and said first and second identifiers associated therewith, said receiving and storing means correlating said code stored in said acquiring and storing means with a corresponding set of said conversion information stored in said receiving and storing means by providing a combination of mnemonic information from said tables in response to portions of code as stored in said acquiring and storing means; and means for acquiring said corresponding set of said conversion information from the receiving and storing means and for presenting said corresponding set of said conversion information to said user for interpretation thereof.
