SYM3D plots an ASCII string (see SYMBOL) in 3-d using PLOT3D. The symbols are plotted in the plane defined by a,b,g.
CALL SYM3D (x,y,z,a,b,g,s,n)
x,y,z (R): lower-left corner of string
If x=999, y=999, z=999 then string is continued from
lower right of previous SYM3D or NUM3D call
a,b (R): angles from the x-y, x-z planes (in deg) of the ray
from (x,y,z) along the base of the character string
g (R): angle of rotation about the ray defined by a,b (deg)
h (R): height of the string to be plotted
s (C): text to be plotted
n (I): number of characters in string s
