NM and CM callable.
Positions the logical record pointer to the relative record number
according to the key sequence.
Operation Notes |
 |
Split stack calls are permitted.
When the relative record number is specified, be sure not to confuse
this number with the chronological record number (the number of the record
as it is stored in the file). The relative record number is based on
the value of a specified key, not its location in a file.
(KSAM/3000) If FFINDN is used to position the pointer before calling another
procedure that reads or updates the file in a shared
environment, FLOCK must be called before calling FFINDN.
After performing the read or update operation, unlock the file.
If the file is locked after calling FFINDN, another user
can change the pointer position without your program being aware of it.
