SYNTAX            : ARG <

RESULTING ARGUMENT: None

FUNCTION          : Execute all single commands within the command sequence
                    up to the corresponding > the specified number of times.

ARGUMENT          : The number of times to execute the iteration. An argument
                    of -1 indicates an infinite amount.

DEFAULT           : -1 (infinite)

EXAMPLE           : 3 < l d >
                    Remove the first character of the following three lines.

NOTE 1            : Iterations can be nested without limitation.

NOTE 2            : If a double-ESC termination is encountered and the
                    corresponding > is missing, an error is reported, and
                    the command sequence aborted. Note, that the body of the
                    iteration up to that point will have been executed once
                    (unless, of course, the iteration-count was zero).

NOTE 2            : The only controlled exits from an iteration are:
                    1) the iteration-count being reached
                    2) via the ; -command.
