PPOST (WKID, STRID, PRIORT)
INTEGER WKID INTEGER STRID REAL PRIORT
The value of PRIORT defines the relative importance of the structures at display. The smaller the PRIORT value, the higher the display priority.
Example :
CALL PPOST (WKID, STRID1, 1.0)
CALL PPOST (WKID, STRID2, 0.0)
CALL PRST (WKID, PALWAY)
With this example, PRST first draws structure of STRID2 identifier, then structure of STRID1 identifier
