Table of Dsgrid control parameters


The following table summarizes all of the parameters used for controlling the behavior of Dsgrid.

Values for these parameters can be set by using the subroutines DSSETI, DSSETR, DSSETRD, and DSSETC for Fortran programs or the functions c_dsseti, c_dssetr, c_dssetrd, and c_dssetc for C programs.
