15.59.8  Examples 

You read in a mesh of X,Y vs Z.
     TD:PROJECT Y FROM 5 TO 10
Projects  the Y slices corresponding to Y=5 to 10 onto the X axis, and 2-d
array of values is stored.  The new array of values is the sum  of  all  Z
values  corresponding  to  the  range  of  Y  values.   The  mesh  data is
destroyed.
     TD:PROJECT Y FROM 5 TO 10 BY 2
Makes 3 projections from 5 to 7, 7 to 9, and 9 to 10

     TD:PROJECT X Y APPEND
     TD:SET WINDOW X 1 of 2;HIST SET <SETS-1>;TITLE BOTTOM 'X axis'
     TD:SET WINDOW X 2 of 2;HIST SET LAST;TITLE BOTTOM 'Y axis'
     TD:DELETE SETS FROM <SET-1>
Projects both X and Y.  The projection along the X axis is in data next to
last data set while along Y is in the last set.  Both projections are then
histogrammed in separate windows.  Finally the projections are deleted.
Note:   This  assumes  only  1 mesh data set exists.  If n mesh sets exist
then 2n projections will be formed.

     TD:PROJECT X 1 2.5 X 3 5 X 6 10;HIST
Projects  3  different  bands of data along the X axis.  All 3 projections
are then histogrammed.
