SYNCHRONOUS INPUT/OUTPUT STATEMENT ANALYTIC PROCESSING SYSTEM

摘要

PURPOSE:To improve the execution efficiency of a program by converting synchronous input/output statements into asynchronous input/output statements. CONSTITUTION:The analytic processing system for synchronous input/output statements in a source program 10 described in FORTRAN language having an asynchronous input/output function has an input/output statement analyzing means 21 which performs analytic processing as to read synchronous input/ output statements, an input/output statement converting and deciding means 22 which decides whether or not they can be converted into asynchronous input/ output statements, and an input/output statement converting means 23 which converts the synchronous input/output statements into the asynchronous input/ output statements according to information obtained by the analytic processing when the conversion is possible.
