- 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..
