Subroutine

2020

This chapter presents the concept of the subroutine. This concept came from the EDSAC (Electronic Delay Storage Automatic Calculator) project under the term “closed subroutine” Thanks to the subroutine, it is possible to implement the concepts of function and procedure of High-Level (programming) Language (HLL) such as C or PASCAL. To be able to do this, a memory called a stack is required. Its operation, as well as that of its subroutine, are studied. Stack memory simply means the stack as well as the LIFO (Last-In/First-Out) buffer to indicate the order of data circulation. A subroutine is a block of instructions that is executed following a call from a calling subroutine. The chapter, after introducing how the stack and LIFO memory access operates, explains how subroutine makes it possible to implement a higher-level language function or procedure.

Abstract There are number of excellent commercial libraries of mathematical subroutines. Below we list those offering software for optimization, linear and nonlinear least-squares problems, singular-value decomposition, ovenletermined systems of linear equations, systems of nonlinear equations, sparse linear solvers and the finite-element method•

Subroutine Bound

Jonathan D. Istok · Water resources monograph · 1989

Subroutine BOUND inputs specified values of the field variable (hydraulic head, pressure head, or solute concentration) and specified values of either groundwater flow or solute flux, for selected nodes in mesh.These values are used to represent Dirichlet and Neumann boundary conditions for the groundwater flow and solute wansport equations.11.2 INPUT Specified values of the field variable are read "free-format" from the user-supplied file assigned to unit "INF".INF is passed to the subroutine through a labeled common block contained in the f'fie "COMALL" (See Chapter 7 for a listing of COMALL).Then specified values of either groundwater or solute flux are read from INF. 11.3 OUTPUT Specified values of the field variable (hydraulic head, pressure head, or solute concentration) and either groundwater flow or solute flux are written to the user-def'med file assigned to unit "OUTF".Column headings are added to the list of specified values written to OUTF.The character variables "LABELl" and "LABEL2" are used to label the column headings on OUTF as "HYDR_AULIC HEAD", "PRESSURE HEAD", or "SOLUTE CONCENTRATION"and "GROUNDWATER FLOW" or "SOLUTE FLUX".
