Description |
INDEXED |
A fixed record length file that can contain a dynamic number of records that can be accessed in sequential or random order. |
SERIAL |
A sequential file with variable length records and a dynamic file size. |
DIRECT/SORT |
Selecting this file type and setting the Record length to a value greater than 0 creates a DIRECT file. These files have a fixed number of records and fixed record length. DIRECT files have been largely superseded by MKEYED files but are often needed to describe existing files. |
STRING |
A file that contains a continuous string of characters, has no defined records, and grows dynamically as it is written. Also known as an ASCII file. |
DIRECTORY |
A DIRECTORY file contains lists of file names. Directory files can only be accessed as read-only sequential-access files. They cannot be created by using the Make command. |
MKEYED |
A single-key MKEYED file is created if a value is entered in the KeySize field, or a multiple-key MKEYED file is created if the Key Size field is set to 0. |
C-ISAM |
Keyed files similar to MKEYED files that are compatible with INFORMIX C-ISAM files. |
