I have found this rather useful Commodore 64 Reference Guide which has the following useful sections in just three small pages.
The doc covers:
- COMMODORE FILE TYPES AND USES
- COMMODORE 64 BASIC DISK COMMANDS
- COMMODORE 128 BASIC DISK COMMANDS
- COMMODORE DOS WEDGE DISK COMMANDS
- DATEL ACTION REPLAY DISK COMMANDS
- JIFFY DOS DISK COMMAND ON FUNCTION KEYS
- STANDARD JIFFYDOS COMMANDS
- IDE64 DISK COMMANDS
- IDE64 COMMODORE BASIC COMMAND EXTENSIONS
It was on my rather old mobile phone and I have no way of knowing who authored it, so if you do know, please inform me and I will credit them 🙂
Commodore 64 and 128 Disk Commands Reference Guide (PDF)
A handy three page Commodore 64 and 128 reference guide covering file types and disk commands for C64 BASIC, C128 BASIC, the DOS Wedge, Datel Action Replay, JiffyDOS and IDE64. The original author is unknown; if you know who made it, let Mark know so they can be credited.
