'''On File(2024)''' 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 projects developed for '''CP/M 2.2'''. As per [[Cosmos]], On File has been developed on the basis of the hardware peripherals as well as the software that were (contemporary) available for the CP/M and the CPC6128. However, it can run on a standard single drive CPC6128. On File database is efficient, quick and reliable and can be used on an everyday basis using the CPC emulators. It uses the entire CPC screen as the platform for the records; thus there is plenty of space to edit user-defined fields. In addition, a wide variety of characters and symbols can be included in the fileds, hence the records can contain data beyond the typical and traditional text type. On File 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. On File (2024) projects developed database has maximum capacity of 200 records (400 KB). The original disk contains the boot sectors for CP/M2.2 (Dobbertin v1.2 for 128 KB RAM), a few demo master records (*.002 files), a few database examples, the application (COM file), as well as the color screen saver (CHN file).

'''On File database is efficient, quick and reliable. It uses the entire CPC screen as the platform (2025)''' Database Management System for the records; thus there is plenty of space to edit large amount of data'''CP/M plus''' was released in June 2025. In additionto the 2024 version, a wide variety of characters it includes the options to Group and symbols can be included in to Invert the records, hence to Index the database can contain data beyond the typical , to perform Index based search and traditional text typeto perform field based calculations. Setting up a new database using It also supports [[GSX]], '''field-based graphics''', unlimited number of Relational Keys and On Board help. It also includes '''On File is very easy and can be performed in three steps: <br><br> 1) start the new file system by resetting the database and the master recordRegister''', <br><br> 2) frame/draw and edit the structure a RAM-disk based register book. The latter provides capacity for a few thousands of the master record, <br><br> 3) append new single-field records . On File 2025 requires RAM expansion to run and includes a resume option in order to access the database on the basis of the master recordRAM-disk contents upon restart. <br><br> The database is fully dynamic, thus the user can modify the master record as well as any record anytimeoriginal disk contains CP/M plus boot sectors (Dobbertin v1. Furthermore1x), the a database can be either flat or relational. Children records include the ^ symbol followed by the relational key of old computers and one space, a register book for example ^Z80 . Parent records include the relational key (not the ^ symbol) followed by one space, for example Z80 period 1970-1989. On File database (2024/2025) is disk-based and every record has its own unique filename, thus all the records are stored in the disk driveas stand-alone files. On the other hand, On File capacity is 200 Register uses a single file to store the records (equal to 400 in the RAM-disk. For large register books which contain more than 64 records, a 16 KB), it "cache" memory is thus an ideal application for implemented in order to be able to move back and forth while reading the 20 MB [[Dobbertin Harddisc]] which supports up to 512 file entries as well as [[ROMDOS]] or [[ParaDOS]] 80 track disksrecords. As per [[Cosmos]]Notice, On File has been developed on that in the basis of all 2025 version, in order to maximize the hardware peripherals as well as free directory entries and to overcome the software that were (contemporary) available for the CP/M Compiler and the CPC6128. The original disk contains some demo master records (*.002 files)Editor Overflow, some demo records as well as a big part of the boot sectors for CP/M 2.2 On File source code (v1ONFILE.2COM). <br><br> has been '''On File Register Bookencapsulated in the source code''' of the Register Book (On File extensionREGISTER.COM) which runs using the RAM-disk will be released in summer 2025. It and is RAM-disk based and single filed, thus it provides practically endless capacity for 128 byte records. Hence, the accessed upon 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 request via boolean expressions that were stronger than 6 Richter using On File Database. As per [[Cosmos]], On File Register has a resume option are temporarily stored in order to access the RAM-disk contents anytime and it also supports the On File screen saver.
