SYSGBL is a privilege that allows a process to create or delete system global sections by executing the Create and Map Section ($CRMPSC) or the Delete Global Section ($DGBLSC) system service. In addition, a process with this privilege (plus the CMKRNL and PRMGBL privileges) can use the Install utility (INSTALL).

System global sections require space in the global section and global page tables, which are limited resources.
