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..
