TCL-I Commands

TCL-I commands are a set of general-purpose commands that do not require the user to specify the name of a file. (These commands may access various system files to get information, but the user does not need to identify the file.) In general, these commands do not support parenthetical options, except where specifically allowed. Listed below are several TCL-I commands:

BLOCK-PRINT

Displays a character string using block letter definitions in the BLOCK-CONVERT Dictionary.

DUMP

Lists the contents of one or more frames.

ECHO

Controls whether or not user input is echoed on the terminal display screen.

MSG

Sends a message to users of a specified account or line, or to all users or all lines.

P

Suppresses or permits (toggle) output to terminal.

SET-INPUT0

Provides R91 compatibility for the mvBASIC INPUT,0 command.

SLEEP

Suspends a process for a specified number of seconds or until a time-of-day specified.

TERM

TIME

WHO

A set of TCL-I commands define the user environment:

DEBUG-ON
