For each subroutine CROSS tabulates: the subroutine name and size, entry points, listed but unused symbols, uninitialized variables, unreferenced statement numbers, internal statement numbers of input-output statements, symbols which appear in input-output statements, called subroutines, and the active variables in common and/or equivalence blocks, together with block names and addresses. CROSS lists common and/or equivalenced variables in alphabetic order with addresses and corresponding block names, along with the names of routines in which these variables are actively used. Any suspicious-looking or inconsistent items are flagged. The same information will also be sequenced and listed according to block names and addresses within each block. CROSS also produces a table designed to show instantly which routines need attention because SLOP found errors in them, which are missing or defined more than once, which routines are calling each routine, and how many times each routine is being called by the other. Finally, if any cycles of subroutine calls are detected, a second table indicating these recursive calls will be produced. The test case supplied with this package is designed to be self-explanatory, removing the need for separate documentation.IBM360,370,303x; PL/I; OS/360; 600K bytes of storage are required.« lessPrograms NAES and SS: user-oriented programs for solving nonlinear algebraic equations and ordinary differential equations. [In FORTRAN IV]Technical Report McCue, H. Program NAES (Nonlinear Algebraic Equation Solver) is a Fortran IV program used to solve the vector equation f(x) = 0 for x. Two areas where Program NAES has proved to be useful are the solution for initial conditions and/or set points of complex systems of differential equations and the identification of system parameters from steady-state equations and steady-state data. Program SS (State Space) is a Fortran IV program used to solve a system of first-order, ordinary differential equations with a minimum of specialized coding. Program SS automatically provides a tabular listing and line-printer plots of the outputs. In addition, provisionsmore » are made to perform one-time preintegration calculations, read specialized input data, establish specialized output labels, handle piecewise continuous f(x(t),t), make x--y plots of output variables, and record the minima/maxima of specified variables. Subroutines were written to provide delay, level detection with hysteresis, and solutions to implicit equations. 26 figures, 1 table. |
