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
