semicolon separator
semicolon separator. A sequence of two or more characters where the first one is a
semicolon, and the remaining ones are spaces.
sentence. A sequence of one or more statements, the last terminated by a period (.).
separately compiled program. A program that (together with its contained programs) is
compiled separately from all other programs. In the HP COBOL implementation,
several separately compiled programs can be presented to the compiler as a group;
each must be separated from its neighbor by an ENDUNIT directive or its end program
header.
separator. A string of one or two punctuation characters used to delimit character-strings.
sequential access. An access mode in which a process reads logical records from or
writes logical records to a file in a consecutive predecessor-to-successor sequence
determined by the order of the records in the file (or, in the case of sequential access
by an alternate record key, in a sequence governed by the value of the alternate key
selected in a START statement).
sequential block buffering. An Enscribe feature, enabled by the RESERVE clause of the
FILE-CONTROL paragraph, that speeds the reading of a sequential, relative, indexed,
or queue file by reading a block of records together into a memory buffer.
sequential file. A file that has sequential organization (includes entry-sequenced and
unstructured files).
sequential organization. A permanent logical file structure in which a process identifies a
record by a predecessor-successor relationship established when the same or another
process writes the record to the file.
server. A process that handles database input and output and related logical and
computational operations specified by a requester.
session. The period of time between a command interpreter
LOGON command and the
next LOGON or LOGOFF command; certain environmental attributes, such as the
current default system, volume
, and subvolume, selected debugger, and saved
ASSIGN and PARAM messages persist until you explicitly change them or issue the
LOGOFF command to end a command interpreter session.
shared code. See position-independent code (PIC).
shared run-time library (SRL). A collection of procedures whose code and data can be
loaded and executed only at a specific assigned virtual memory address (the same
address in all processes). SRLs use direct addressing and do not have run-time
resolution of links to and from the main program and other independent libraries.
Compare to dynamic-link library (DLL).
