Concise Command Language (CCL) was the term used by Digital Equipment Corporation for the Command-line interpreter / User interface supplied on several of their computing systems; its successor was named DIGITAL Command Language (DCL).
CCL provides the user with an extensive set of terminal commands.[1]
The first system to include CCL was DEC's PDP-10.
The PDP-6 monitor came with a simple set of commands. To compile and run a FORTRAN program, one would
(The DOT is a monitor prompt and the Star/Asterisk is an application prompt)
The PDP-10 had CCL. Key to its improvements over its predecessor were:[2]
The following table contains a list of CCL commands.
| CCL command (full form) | CCL command (short form) | Description | |
|---|---|---|---|
| BACKSPACE | BAC | Runs CAMP. A magnetic tape or cassette is spaced backward a specified number of files or records. | |
| BOOT | BO | ||
| CCL | CCL | Disables the CCL program on the OS/8 Keyboard Monitor residing on the system device. | |
| COMPARE | COMP | Runs SRCCOM. Compares/shows differences between two source files. Although line by line, permits "catch up." | |
| COMPILE | COM | Produces binary files and/or compilation listings for specified program files. | |
| COPY | COP | Transfers files from one I/O device to another. | |
| CORE | COR | ||

| CREF | CREF | ||
| DATE | DA | ||
| DEASSIGN | DEA | ||
| DELETE | DEL | Deletes one or more files from disk or DECtape. | |
| DIRECT | DIR | ||
| EDIT | ED | Runs EDIT. Opens an already existing file for editing. | |
| EOF | EOF | ||
| EXECUTE | EXE | ||
| HELP | HE | Prints information on specified OS/8 programs. | |
| LIST | LI | ||
| LOAD | LO | ||
| MAKE | MAK | Runs TECO. Opens the specified file for output. | |
| MAP | MAP | Runs BITMAP. | |
| MUNG | MUNG | Runs a TECO Macro; command line parameters give added adaptability. | |
| PAL | PAL | Runs PAL8. Assembles the source file specified as the argument. | |
| PRI | Runs a program named LPTSPL. | ||
| PUNCH | PU | Runs PIP. Punches the file specified on paper tape. | |

| REWIND | REW | ||
| SKIP | SKIP | ||
| SQUISH | SQ | Runs PIP's "squeeze" / defrag tool | |
| SUBMIT | SU | Runs the BATCH program. | |
| TECO | TE | (Text Editor and COrrector, a sophisticated text editor with MACRO capabilities). | |
| TYPE | TY | ||
| UA | UA | ||
| UB | UB | ||
| UC | UC | ||
| UNLOAD | UNL | ||
| VERSION | VER | Prints the version numbers of the OS/8 Keyboard Monitor and CCL. | |
