The maximum number of records in one file is 65,533. Records are usually called items in CMS terminology. CMS files can have either fixed or variable record format; record types may not be mixed in a file. For fixed-length records the length is defined by FSTLRECL, and the location of any fixed-length record can be computed by (item_number-1 ...
Commodore DOS, also known as CBM DOS, is the disk operating system used with Commodore's 8-bit computers.Unlike most other DOSes, which are loaded from disk into the computer's own RAM and executed there, CBM DOS is executed internally in the drive: the DOS resides in ROM chips inside the drive, and is run there by one or more dedicated MOS 6502 family CPUs.

The drive stores 800 kilobytes using an MFM encoding [5] but formats different from the MS-DOS (720 kB), Amiga (880 kB), and Mac Plus (800 kB) formats. With special software it's possible to read C1581 disks on an x86 PC system, and likewise, read MS-DOS and other formats of disks in the C1581 (using Big Blue Reader), provided that the PC or ...
An even later development was the application of CBM to middle-secondary areas: Espin and colleagues at the University of Minnesota developed a line of research addressing vocabulary and comprehension (with the maze) and by Tindal and colleagues at the University of Oregon developed a line of research on concept-based teaching and learning.
