Data Files for Persistence
In general, all data files consist of newline ("\n") delimited records.
Each record in turn is delimited by a ":" character (these choices are
arbitrary and can easily be changed). All fields in a record are
single-valued (ie normalized). If the value of a field cantains the
record separator character, it must be escaped using the " character
(see the adapter file).
- syntax
Describes the schema in all subsequent files. Fields are
defined as follows:
syntax the syntax to use for subsequent access
tabname a table (ie file)
colname a column (ie field) in that file
colseq the order of the column
iskey 1=column participates in a PRIMARY key
