Notes

(a)

GROPN sets  the internal variable 'IWS' using SGISTX, and executes sginit. Therefore, the internal variable 'IWS' handled by sgpget/sgpset can be changed using a runtime option. (Hereafter, in this section, the term "internal variable" will refer to an internal variable handled by sgpget/sgpset. )

(b)

Furthermore, GROPN uses SGpSTX to set the internal variable 'LCNTL' to .true..
