'''Good applications are like good songs, they never die.On File'''Database Management System was released in June 2024 by [[KSL]] in order to celebrate the anniversaries of CPC (40 years!) and CP/M-80 (50 years!). On File is a business application similar to the MSDOS-era PC applications and one of the most recent (2024) projects developed for CP/M.
On File database is quick and reliable. It uses the entire CPC screen as the platform for the records; thus there is plenty of space to store large amount of data. In addition, a wide variety of characters and symbols can be included in the records, hence the database can contain data beyond the typical and traditional text type. Setting up a new database using On File is very easy and can be performed in three steps: 1) start the new file system by resetting the database and the master record, 2) frame/draw and edit the structure of the master record, 3) append new records in the database on the basis of the master record. 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 . 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).
'''On File Register Book''' (On File extension) will be released in summer 2025. Thus, the user can set up a Register of e.g Earthquakes (date, time, location, magnitude, depth) using On File Register, while keeping detailed records of the ones that were stronger than e.g. 6 R using On File. As per [[Cosmos]], On File Register has a resume option in order to access the RAM expansion contents anytime and it also supports the On File screen saver.
'''On File''' Database Management System was released database is disk-based and every record has its own unique filename, stored in June 2024 by the disk drive. On File capacity is 200 screen records (equal to 400 KB), it is thus an ideal application for the 20 MB [[KSLDobbertin Harddisc]] in order which supports up to celebrate the anniversaries of CPC (40 years!) and CP/M-512 file entries as well as [[ROMDOS]] or [[ParaDOS]] 80 (50 years!)track disks. On the other hand, On File Register Book is a business application similar to the MSDOSRAM-era PC applications based and one of the most recent (2024) projects developed single filed, thus it provides practically endless capacity for CP/M128 byte records.

'''On File Register BookGood applications are like good songs, they never die.''' (On File extender) which runs using entirely the RAM expansion will be released in summer 2025. In contrast with On File where the record files are disk-based and stand-alone, On File Register Book is RAM-based and single filed, thus it provides practically endless capacity for 128 byte records. Hence, the user can set up a Register of e.g Earthquakes (date, time, location, magnitude, depth) while keeping detailed records of the ones that where stronger than e.g. 6 R using On File. As per [[Cosmos]], On File Register Book has a resume option in order to access the RAM expansion contents anytime.
