1. A data processor utilizing a plurality of parameter tables having various objects to be processed for setting a processing condition and processing data of a particular object to be processed in accordance with a set of the tables, comprising: storage means for storing a measured data processing procedure utilizing said set of tables; table memory means for storing a plurality of tables each including information of a table structure of a table; a central processing unit (CPU) connected to said storage means for processing measured data in accordance with the measured data processing procedure stored in said storage means; input means connected to said CPU for inputting external information to said CPU; output means connected to said CPU for outputting a result of said measured data processing procedure; table generation means connected to said CPU, said input means and said table memory means for generating a table structure in said table memory means based on a table specification description defining a table structure, said table specification description including a table name, item names and a type attribute of the item names and being supplied by said input means; table content setting means connected to said CPU, said input means and said table memory means for setting a desired parameter into a desired table of said table memory means in response to a table setting command input by said input means; and table content reference means connected to said CPU, said input means and said table memory means for referring to a content of a desired table of said table memory means in response to a table reference command input by said input means and outputting from said output means the content referred to by said table content reference means; wherein said table generation means stores an input table name and a number of items into a first table and stores an input item name into a second table in response to said table specification description, and stores in the first table a pointer for pointing to a memory location of said table memory means of the item name inputted to said second table; and wherein said table generation means stores in a column of the input item name of the second table a type attribute and a pointer for pointing to a memory location in said table memory means of an item value table to be stored.
