The hybrid subroutine library contains three subroutines to be used in performing a rectangular integration, RINT$, CNP$, and ICL$. Subroutine RINT$ is used to perform the calculation of the integral and can be used in either synchronous or asynchronous mode. The purpose of CNP$ is for calculation {Delta}t , the time between integral calculations, for an asynchronous integration . Subroutine ICL$ is for initialization of the real-time clock and also contains the save and restore portions of the clock service subroutine
