Apart from the typing keys, the keyboard includes a space bar, two shift keys, a caps lock, a backspace key, margin release key, paragraph indentation key and a tab-stop set/unset key. As was common in older typewriters, it lacks the number 1 (but the Olivetti Lettera 10 has it), which is supposed to be substituted by the lowercase l .
If there is only have one diskette drive, diskcopy can be done by typing the source drive only. The disk copy program will prompt to insert the second (target) diskette once it finishes reading the complete contents of the first (source) diskette track by track into memory.

A disk operating system (DOS) is a computer operating system that resides on and can use a disk storage device, such as a floppy disk, hard disk drive, or optical disc. A disk operating system provides a file system for organizing, reading, and writing files on the storage disk, and a means for loading and running programs stored on that disk.
The command was included as a terminate-and-stay-resident program with MS-DOS and PC DOS versions 5 and later, [4] then Windows 9x, [5] and finally Windows 2000 [6] and later. In early 1989, functionality similar to DOSKEY was introduced with DR-DOS 3.40 with its HISTORY CONFIG.SYS directive. This enabled a user-configurable console input ...
The version included with PC DOS 3.0 and 3.1 is hard-coded to transfer the operating system from A: to B:, while from PC DOS 3.2 onward you can specify the source and destination, and can be used to install DOS to the harddisk. The version included with MS-DOS 4 and PC DOS 4 is no longer a simple command-line utility, but a full-fledged installer.
The previous menu option from DOS 1.0, N. DEFINE DEVICE, was replaced with N. CREATE MEM.SAV in DOS 2.0S. Version 2.0S was for single-density disks, 2.0D was for double-density disks. 2.0D shipped with the 815 Dual Disk Drive, which was both expensive and incompatible with the standard 810, and thus sold only a small number; making DOS version ...
Some programs faked the missing "Fail" response in DOS 2.0 by jumping back to the calling program, skipping the return stack in DOS. This was a risky hack as it relied on the stack layout and skipped cleanup operations in the operating system.
