Below is a copy of the IBM PC DOS 1.00 manual. The original PC DOS 1.00 diskette is also available.
Summary of internal commands:
- COPY
- Copies one or more files to another diskette and optionally, gives the copy a different name if you specify it in the COPY command.
- DIR
- Either lists all the directory entries, or only lists those for specified files. The information provided in the display for each file includes its size in decimal bytes and the date the file was last written to.
- ERASE
- Deletes the file with the specified filename from the designated drive, or deletes the file from the default drive if no drive was specified.
- PAUSE
- Suspends system processing and issues the message Strike·a key when ready....
- REM
- Displays remarks from within a batch file.
- RENAME
- Changes the name of the file specified in the first parameter to the name and extension given in the second parameter. If a valid drive is specified in the second parameter, the drive is ignored.
- TYPE
- Displays the contents of the specified file on the screen.
Summary of external commands:
- BASIC
- Also known as Disk BASIC, this program requires an IBM PC with Cassette BASIC and at least 32Kb of RAM.
- BASICA
- Also known as Advanced BASIC, this program requires an IBM PC with Cassette BASIC and at least 48Kb of RAM. It includes all Disk BASIC features, along with event trapping, advanced graphics, and advanced music support.
- CHKDSK
- Analyzes the directory and the File Allocation Table on the designated or default drive and produces a diskette and memory status report.
- COMP
- Compares the contents of one file to the contents of another file.
- DATE
- Permits you to enter a date or change the date known to the system. The date is recorded in the directory entry for any files you create or alter.
- DISKCOMP

- DISKCOPY
- Copies the contents of the diskette in the source drive to the diskette in the target drive.
- FORMAT
- Initializes the diskette in the designated or default drive to a recording format acceptable to DOS; analyzes the entire diskette for any defective tracks; and prepares the diskette to accept DOS files by initializing the directory, File Allocation Table, and system loader.
