^e
end of line

^v

^q

Options may be specified in the file %HOME%\spcmd.ini as: 

     Option Value

on separate lines. Recognized options are:

lines
Value is the number of lines in the history buffer. 1-100 is accepted; the default is 30.
save
Value is either 0 (don't save or restore history buffer) or 1 (save history buffer in %HOME%\spcmd.hst on exit, restore history from the same file on start up.

The command line editing is switched off by giving the option -nocmd when starting SICStus. Command line editing will be automatically turned off if SICStus is run with piped input (e.g. from Emacs).
