The relative position of a
prime block in a file. Ordinal numbers start at zero.
organization
In the TPFDF product, the
ascending (UP) or descending (DOWN) sequence of logical records (LRECs) in a
subfile. If a subfile is organized, the TPFDF product can access the
LRECs without necessarily reading the whole subfile. The database
administrator specifies how a file is to be organized by coding the DBDEF
macro instructions that define the file.
overflow block
Any block in a subfile that
is not a prime block. A subfile can contain zero or more overflow
blocks, which are always pool records. See also prime block
and pool file.
