.TH NNGETASPECTD 3NCARG "March 1997-1998" UNIX "NCAR GRAPHICS"
.SH NAME
NNGETASPECTD - retrieve the double precision aspect at a specified coordinate.
.SH SYNOPSIS
CALL NNGETASPECTD (I,J,ASPECT,IER)
.SH DESCRIPTION
.IP I 12
(Integer, Input) - A subscript indexing the first dimensioned variable 
in the output grid of the most recent call to NATGRIDD. 
.IP J 12
(Integer, Input) - A subscript indexing the second dimensioned variable 
in the output grid of the most recent call to NATGRIDD. 
.IP ASPECT 12
(Double precision, Output) - The slope at the 
grid point Z(I,J), where Z is the 
output grid in the most recent call to NATGRIDD. 
.IP IER 12
(Integer, Output) - An error return value. If IER is returned as 0, then 
no errors were detected. If IER is non-zero, then refer to the man
page for natgrid_errors for details.
