Reset the state of PONGO.


The state of PONGO (global parameter values, AGI and PGPLOT) is returned to a default state: all global parameters are reset to their default values, the AGI database for the graphics device is cleared, and the viewport is reset to the standard PGPLOT viewport. The global parameter values for the PONGO data file (PONGO_DATA) and the polynomial coefficients (PONGO_POLYCOEF) are not reset.

This command is an ICL hidden procedure using the SETGLOBAL command and the CHANGE, CLEAR, VIEWPORT and WORLD applications.
