1 /GLOBAL_SECTION
/GLOBAL_SECTION (default) /NOGLOBAL_SECTION /NOGLOBAL_SECTION indicates that the memory qualifier is for a privileged application instead of a group or system global section. (/GLOBAL_SECTION indicates that the memory qualifier is for a group or system global section.) You cannot use /NOGLOBAL_ SECTION with the qualifiers /GROUP, /SYSGBL, or /PAGE_TABLES.
2 /GROUP
/GROUP=n You must specify /GROUP if the memory-resident global section is a group global section. Do not specify /GROUP if the memory- resident global section is a system global section. The value n is the UIC group number (in octal) associated with the memory- resident being freed. You cannot use the /GROUP qualifier with either /SYSGBL or /NOGLOBAL_SECTION qualifiers.
3 /SYSGBL
Indicates that a reservation is for a system global, memory- resident section. You cannot combine this qualifier with the /GROUP or /NOGLOBAL_ SECTION qualifier. This qualifier is the default unless you specify /GROUP or /NOGLOBAL_SECTION.
