FTAM-1 file.
FTAM-1 file. An unstructured text file that can be accessed only as a single data unit. See
also document type.
FTAM-2 file. A sequential text file that can be accessed either as a single data unit or as
multiple data units. See also document type.
FTAM-3 file. An unstructured binary file that can be accessed only as a single data unit.
See also document type.
FTM procedures. The set of procedure calls whose names begin with “FTM”, provided with
NonStop FTAM to support the FTAM protocol. The FTM procedures are defined in the
EXTDECS0 and CEXTDECS files. The FTAM API consists of the FTM procedures plus
the MFM procedures, a subset of the APS procedures, and associated definition files.
See also API (application programmatic interface).
functional unit. In OSI terms, a collection of service primitives needed to provide one of the
major optional styles of working, such as file access or enhanced file management.
Functional units are negotiated at association establishment. Functional units
determine which sets of FTAM services are available for an association, depending on
which service class is negotiated.
FUP (File Utility Program). A NonStop utility program that can be used to perform many
functions on disk files and peripheral devices such as tape drives. For example, you
can use FUP to create and purge files, duplicate and display files, alter file
characteristics such as security attributes, and load data into files.
future-filesize attribute. A file attribute that specifies the size limit (in octets) for
modification or extension of the file. The future-filesize attribute is related to the
NonStop 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.
