SUBROUTINE PICK2D (PROMPT, CURSOR, MIDDEF, IFLD, INTYP, RFIELD,
& XRES, YRES, *)
C=======================================================================
C --*** PICK2D *** (MESH) Pick a window point
C -- Written by Amy Gilkey - revised 02/05/88
C --
C --PICK2D picks a user-selected window point. For cursor input, PICK2D
C --puts a cursor on the screen, waits until the user positions the cursor,
C --then translates the position into a 2D point. For character input,
C --PICK2D gets an X,Y pair from the free-format fields (defaults are
C --not allowed).
C --
C --Parameters:
C -- PROMPT - IN - the point requested
C -- CURSOR - IN - true iff cursor input
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 -- (cursor input only)
C -- IFLD - IN/OUT - the free-format field index (character input only)
C -- INTYP - IN - the free-format field types (character input only)
C -- RFIELD - IN - the free-format real fields (character input only)
C -- XRES, YRES - OUT - the returned point
C -- * - return statement if error picking point
C --
C --Common Variables:
C -- Sets DXLAST, DYLAST of /PICK/
C -- Uses /PICK/
