SAVEPOSITION Procedure
(Superseded by FILE_SAVEPOSITION_ Procedure)
Considerations
•
For relative and entry-sequence files that have no alternate keys. SAVEPOSITION
requires a 7-word
positioning-block if read-reverse is the current reading
mode (see the KEYPOSITION[X] procedures).
•
The SAVEPOSITION procedure cannot be used with format 2 files. If an attempt
is made to use the SAVEPOSITION procedure with format 2 files, error 581 is
returned. See the FILE_SAVEPOSITION_ Procedure
for information on how to
perform the equivalent task with format 2 files.
•
In files that support insertion-ordered duplicate alternate keys, each alternate key
includes four additional words for a timestamp.
Example
CALL SAVEPOSITION ( FILE^NUM , POSITION^BLOCK );
