TRANSLATION SYSTEM FOR SOURCE PROGRAM INCLUDING INPUT/ OUTPUT SENTENCE WITHOUT FORMAT

摘要

PURPOSE:To set the processing of data transfer only once and to attain a high speed input/output processing by permitting a user to designate a translation time instruction line immediately before an input/output sentence concerned and to process an input/output list as one variable area. CONSTITUTION:An area assignment means 21 inputs a source program 1, detects the translation time instruction line, and checks whether it is grammatically possible to assign the input/outputs, an appeared variable or the area of an array in an appeared order, or not. Next, an information table generation means 22 takes a series of assigned areas for one variable area, generates information on a position and a length with respect to the variable area concerned and stores them in an information table 24. An object program generation means 23 inputs the information table 24, and generates an object program 4 calling the input/output execution processing means of OS. Thus, it comes to be unnecessary to execute the processing of data transfer for plural times.
