摘要： 在程序设计中,子程序有着独特的优点。然而,过多地调用子程序又必然要花费许多额外代价。为此,我们针对SEG协会提出的一套具有向量特征的子程序设计了预处理器VPPS。它将调用SEG子程序的语句用相应的Fortran Do-循环取代,可以使速度提高近10倍。

Abstract: Subroutines are especially preferable in system programming. However, much overhead is required for too many call-statements. Therefore, a pre-processor VPPS is designed to process vector-subroutines put forward by SEG Institute. It will change the call-statement into Fortran Do-loop statement, so that a new program will be performed 10 times faster.
