<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 every record has its own unique filename, stored in the disk drive. On File capacity is 200 records (equal to 400 KB), it is thus an ideal application for the 20 MB [[Dobbertin Harddisc]] which supports up to 512 file entries as well as [[ROMDOS]] or [[ParaDOS]] 80 track disks. As per [[Cosmos]], On File has been developed on the basis of all the hardware peripherals as well as the software that were (contemporary) available for the CP/M and the CPC6128. 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> '''On File Register Book''' (On File extension) which runs using the RAM-disk ([[Dobbertin Memory Expansion]]) will be released in summer 2025. It is RAM-disk based and single filed, thus it provides practically endless capacity for 128 byte records. Hence, the user can set up e.g. a Register of Earthquakes (date, time, location, magnitude, depth) using On File Register, while keeping detailed records of the ones 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.
