Changes

<br><br> The database is fully dynamic, thus the user can modify the master record as well as any record anytime. Furthermore, the database can be either flat or relational. Children records include the ^ symbol followed by the relational key and one space, for example ^Z80 . Parent records include the relational key (not the ^ symbol) followed by one space, for example Z80 . On File database is disk-based and has a capacity of 200 records (equal to 400 KB). It is thus an ideal application for the 20 MB [[Dobbertin Harddisc]] which supports up to 512 directory entries as well as [[ROMDOS]] D20 80 track disks, which can store up to 256 records in a single user (tested and working using On File)as well as the 20 MB [[Dobbertin Harddisc]] which supports up to 512 directory entries. The original disk contains some demo master records (*.002 files), some demo records as well as the boot sectors for CP/M 2.2 (v1.2). <br><br> In summer 2025 a new version of On File will be released. It will provide capacity for 230 records (460 KB) and will also include '''On File Register''', a RAM-disk single-file register book. The latter will provide capacity for a few thousands of single-field records. Hence, the user can set up e.g. a Register of Earthquakes (date, time, location, magnitude, depth and duration) using On File Register, while keeping detailed records of the earthquakes that were stronger than 6 Richter using On File Database. As per [[Cosmos]], On File Register has a resume option in order to access the RAM-disk contents anytime and it also supports the On File screen saver.
