Compaq max-extents attribute: modifying the future-filesize attribute changes the max-
extents attribute, and vice versa.
GeneralString. The character-string type of strings containing any of the characters for
all G sets and all C sets (as defined by ISO 2022), the space character, and the delete
character. These strings contain format effectors.
GraphicString. The character-string type of strings containing any of the characters for
all G sets (as defined by ISO 2022) and the space character. These strings do not
contain format effectors.
grouped procedure. An FTM procedure that allows an application to perform several
file operations as a grouped service. The grouped procedure FTM_FILE_OPEN_REQ_
allows you to create, select, and open an FTAM file as a grouped service. The grouped
procedure FTM_FILE_CLOSE_REQ_ allows you to close and either deselect or delete
an FTAM file as a grouped service. See grouped service.
grouped service. A sequence of confirmed services that are requested in one FTAM
event, and for which the responses are received as one event. The request primitives for
these services are bracketed with the F-BEGIN-GROUP and F-END-GROUP request
primitives. See also grouping control.
grouping control. A mode of operation that allows your application to perform a
sequence of confirmed services in one FTAM event. The request primitives for these
services are bracketed with the F-BEGIN-GROUP and F-END-GROUP request
primitives. The grouped request primitives are concatenated and sent in a single request
PDU. The responder analyzes and retains its response to each of these requests until the
group is complete or until a state failure occurs. The responder then returns its
responses as a group.
grouping functional unit. A functional unit that provides for the combination of several
independent primitives in order to establish several regimes in one exchange.
Guardian . The original application program interface (API) to the Compaq NonStop
Kernel.
Guardian environment. The Guardian API and the Compaq NonStop tools. Referred
to as “personality” in marketing literature.
Guardian process name. The external name by which the Compaq NonStop Kernel
identifies a process. This name is assigned when a process is created using the NAME
attribute. To operate on a Compaq Expand network, this name must be a maximum of
five ASCII characters, including the initial dollar sign ($).
hierarchical file model. A file structure with the following characteristics:
•
The file-access structure is an ordered tree.
•
Each node within the structure is assigned zero or one data unit.
•
Each node provides access to its subtree.
•
A node can, optionally, be named.
