C --Parameters:
|
||
|
|
C -- PROMPT - IN - the point requested
|
||
|
|
C -- NUMNPF - IN - the number of nodes
|
||
|
|
C -- XN - IN - the x coordinates of the nodes
|
||
|
|
C -- yN - IN - the y coordinates of the nodes
|
||
|
|
C -- MIDDEF - IN - true if the middle of the displayed mesh is to be the
|
||
|
|
C -- starting position, else use the last selected position
|
||
|
|
C -- NDRES - OUT - the node id selected
