echo command The echo command turns terminal character echo on or off. When terminal echo is off, characters entered from the keyboard are not displayed on the terminal screen.
edit command (TCL commands) The edit command invokes the line editor for entry or update of any item in the system (that is, BASIC programs, Procs, data items, and so on).
edit-list command The edit-list BASIC program retrieves a previously saved list and enters the line editor (same as ed oredit). Each element in the list is treated as a line by the line editor; all of the line editor edit commands are valid. For using the Update processor to update saved lists.
encrypt-file command The encrypt-file command encrypts data in a specified file.
end command (TCL commands) The end command terminates a process on another port, or the current port if a port number is not specified.
enqueue-status command The enqueue-status command displays information about the state of the local transaction logging disabled flag for either a specified line or all lines currently logged on.
environ command The environ command manipulates the UNIX shell environment variables from TCL.
esc-data command The esc-data BASIC program specifies that the code generated by pressing ESC (control [) is to be passed through as data.
esc-level command The esc-level BASIC program specifies that pressing ESC pushes a level. The esc-level command uses the set-esc command to enable the special escape key. Without any argument, the usual escape value (x'1B' or 27) is assigned to the level pushing function. The optional argument defines an alternate value.
esc-toggle command The esc-toggle BASIC program turns the function of the ESC key to either be treated as data (esc-data) or as a level-pushing mechanism (esc-level).
estimate-count command The estimate-count BASIC program displays a fast estimate of the number of items in a file.
exchange command The exchange BASIC program switches item-IDs of the two specified items following the file reference.
exec command The exec command runs the current process on the specified ABS area. This has the effect of changing the environment of the D3 Virtual operating system for this process, until log off time. At log off, the abs file is automatically reset to the dm,abs, file.
exec-stacking-off macro The exec-stacking-off macro disables nested executes to be performed in an atomic manner.
exec-stacking-on macro The exec-stacking-on macro enables nested executes to be performed in an atomic manner.
exit command The exit command logs the D3 process off and disconnects it from the D3 virtual machine. Even if the command exit does not exist, the system still exits with the proper privileges.
export command The export command exports D3 items to UNIX files.
