TOPS-10 Survival Guide


TOPS-10 was an operating system for Digital Equipment Corporation's PDP-10 family of mainframe computers (including the DECsystem-10 and DECSYSTEM-20 product lines). TOPS-10 was first released in 1970 and the last release was in 1988.

LCM+L currently has two TOPS-10 systems available on-line:

Host Model/Processor Operating system
dec-10 DECSYSTEM-2065 / KL10 TOPS-10 version 7.04
ki587 DECsystem-1090 / KI10 TOPS-10 version 6.3

Command format: TOPS-10 commands are one to six characters long. At the command prompt ., type the command string or a unique prefix followed by command arguments if any, then press the Enter key to execute the command. In version 7.04 commands are case-insensitive; in version 6.3 all entered command text is automatically converted to upper case.

File name format: TOPS-10 files are identified with a file name from one to six characters long followed by a period (.) and a zero to three character file extension. Many commands allow wildcard characters * (matches any zero or more characters) and ? (matches zero or any one character) in file name arguments to operate multiple files.

Files with standard extensions are given special treatment by some commands.

Ext. File contents Ext. File contents
ALG ALGOL language source EXE Executable binary program
BAS BASIC language source FOR FORTRAN language source
BLI BLISS language source MAC MACRO assembly language source
CBL COBOL language source REL Relocatable binary file

Special characters: TOPS-10 recognizes the following special characters to assist with input and output from the system.

Ctrl-C Interrupt current program and return to TOPS-10.
Delete last input character. (Deleted character is echoed at the end of the input line.)
Ctrl-U Delete current input line.
Ctrl-O Pause/restart terminal output scrolling.
