View source for PRMGBL

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

Global sections are shared structures that can be mapped simultaneously in the virtual address space of many processes. All processes see the same code or data. Global sections are used for reentrant subroutines or data buffers.

If permanent global sections are not explicitly deleted, they tie up space in the
global section and global page tables, which are limited resources.
