14. OTHER PROGRAMMING OR OPERATING INFORMATION OR RESTRICTIONS
Due to the iteractive nature of the calculations in LDEF-SS, machine round-off error may produce slightly different results on different machines.
For the CDC version, the FORTRAN compiler OPTION, ROUND, should be invoked to duplicate the sample problem output. This version includes NESC-provided dummy routines for the LANL Stromberg-Carlson plotter routines: ADV, DRV. GPLOT, GRPHFTN, GRPHLUN, LIB4020, LINCNT, PLT, and SETFLSH, which should be replaced with suitable alternatives for the environment in which the program is being executed to obtain graphical output.
In the IBM3033 version, subroutines DTIME and DATES are written in assembly language; they return the time of day and date information, respectively. Proprietary Calcomp plotting routines PLOT, PLOTS, NEWPEN, WHERE, NUMPEN, and SYMBOL, used to provide the graphic output in the IBM version, are not included and should be replaced with alternatives suited to the local computing environment for graphical output.
