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) database has maximum capacity of 200 records (400 KB). The original disk contains the boot sectors for CP/M 2.2 (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 (2025) Database Management System for CP/M plus was released in June 2025. In addition to the 2024 version, it includes the options to Group and to Invert the records, to Index the database, to perform Index based search and to perform field based calculations. It also supports GSX, field-based graphics, unlimited number of Relational Keys and On Board help. It also includes On File Register, a RAM-disk based register book. The latter provides capacity for a few thousands of single-field records. On File 2025 requires RAM expansion to run and includes a resume option in order to access the RAM-disk contents upon restart. The original disk contains CP/M plus boot sectors (Dobbertin v1.1x), a database of old computers and a register book for the period 1970-1989. On File database (2024/2025) is disk-based, thus all the records are stored in the disk drive as stand-alone files. On the other hand, On File Register uses a single file to store the records in the RAM-disk. For large register books which contain more than 64 records, a 16 KB "cache" memory is implemented in order to be able to move back and forth while reading the records. Notice, that in the 2025 version, in order to maximize the free directory entries and to overcome the Compiler and Editor Overflow, a big part of the On File source code (ONFILE.COM) has been encapsulated in the source code of the Register Book (REGISTER.COM) and is accessed upon user request via boolean expressions that are temporarily stored in the RAM-disk.
What gap of the 80's does On File (2025) come to fill? Let’s give an example. Using On File Register, a register book can be set up with, for example, 5000 citizens of a town. The register book (~210 KB) is saved in disk (disk 0) and is loaded once in the RAM of the CPC6128. Then, using On File Database, a full-screen record can be created for each citizen. The records of the database are saved in 26 different disks (disks A-Z or HD20), depending on the surname of each resident. Notice, that the register book remains in RAM until the end of the work regardless of which disk (A-Z/HD20) is used. Upon exit, the contents of the RAM (register book, if modified) are saved in disk 0. This can be achieved with an Amstrad CPC6128 with 512 KB RAM expansion, a 800 KB external floppy drive, the specific version of CP/M plus (v1.1x), RamDOS D20 disks or HD20.
Using the following two links you can download On FIle (2024) and On File (2025) respectively.
