DOS Random Files
DOS random files are fixed-length files used by the DOS random
read and write routines. The characteristics of DOS random files are
as follows:
- There are no end-of-record or end-of-file markers.
- Records are delimited by their constant length, relative positions in the file, and the total length of the file.
Note: DOS random and DOS random type-2 files are identical,
except for the way in which the signs are represented for packed decimal
and zoned decimal numbers.
