As per '''On File''' Database Management System was released in June 2024 by [[CosmosKSL]], in order to celebrate the anniversaries of CPC (40 years!) and CP/M-80 (50 years!). On File has been developed on is a business application similar to the basis MSDOS-era PC applications and one of the hardware peripherals as well as the software that were most recent (contemporary2024) available projects developed for the CP/M . On File database is disk-based, quick and reliable. It uses the CPC6128: entire CPC screen as the 512 KB [[Dobbertin Memory Expansion]], the [[ParaDOS]] or [[X-DDOS]] ROMS platform for the external (800 KB) floppy driverecords; 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 20 MB [[Dobbertin Harddisc]]records, hence the [[Amstrad Serial Interface]], database can contain data beyond the Amstrad Parallel [[Printer Port]], 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 [[CTM640/CTM644]] colour monitor, new file system by resetting the [[AMX Mouse]]database and the master record, the [[MicroScript]] (142 KB2), frame/draw and edit the [[WordStar]] (706 KBstructure of the master record, 3), append new records in the [[Protext]] (406 KB)database. The database is fully dynamic, thus the [[Multiplan]] (208 KB)user can modify the master record as well as any record anytime. Furthermore, the [[SuperCalc 2]] (240 KB), database can be either flat or relational. Children records include the ^ symbol followed by the [[dBase II]] (272 KB)relational key and one space, for example ^Z80 . Parent records include the [[DR Draw]] relational key (235 KB), not the [[DR Graph]] (306 KB^ symbol)followed by one space, for example Z80 . Every record has its own unique filename, stored in the [[MAXAM]] disk drive. On File capacity is 200 records (206 equal to 400 KB), it is thus an ideal application for the 20 MB [[Atlast PlusDobbertin Harddisc]] (224 KB) and other which supports up to 512 file entries as well as [[Programming softwareROMDOS]]. On File includes a graphics screen saver, is based on the or [[DobbertinParaDOS]] version of CP/M 2.2 disks (v1.128 x 2) which provides 59 KB TPA. Furthermore, supports On File can be also executed entirely from the RAM expansion and the 20 MB hard diskDisk. <br>

As per [[Cosmos]], On File database is disk-based, quick and reliable. It uses has been developed on the CPC screen (80x25) as a single record; thus there is plenty of space to edit many different fields and store large amount basis of data. Setting up a new database using On File is very easy: 1) start the new file system by resetting hardware peripherals as well as the database and the master record, 2software that were (contemporary) frame and/or draw available for the master record, 3) edit the fields CP/M and the structure of CPC6128: the master record512 KB [[Dobbertin Memory Expansion]], 4) append the records in [[ParaDOS]] or [[X-DDOS]] ROMS for the database on the basis of the master record. Every record has its own unique filename, stored in the disk drive. On File capacity is 200 records external (equal to 400 800 KB)floppy drive, it is thus ideal for the 20 MB [[Dobbertin Harddisc]] which supports up to 512 file entries.  The database can be either flat or relational. Children records include , the ^ symbol followed by [[Amstrad Serial Interface]], the relational key and one spaceAmstrad Parallel [[Printer Port]], for example ^Z80 . The relational key can contain up to 15 symbols the [[CTM640/CTM644]] colour monitor, the [[AMX Mouse]], the [[MicroScript]] (A..Z142 KB), a..zthe [[WordStar]] (706 KB), 1..0the [[Protext]] (406 KB),+the [[Multiplan]] (208 KB),?the [[SuperCalc 2]] (240 KB), etc.the [[dBase II]] (272 KB). Parent records include , the relational key [[DR Draw]] (not 235 KB), the ^ symbol[[DR Graph]] (306 KB) followed by one space, for example Z80 the [[MAXAM]] (206 KB), the [[Atlast Plus]] (224 KB) and other [[Programming software]]. If On File includes a record contains more than one relational keygraphics screen saver, is based on the key at [[Dobbertin]] version of CP/M 2.2 (v1.2) which provides 59 KB TPA, supports the lowest field is set as RAM expansion and the active key20 MB hard disk.  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)
