Push "[center]"         ;[center]
                        ;  center string
Push "[delimiter2]"     ;[delimiter2]
                        ;  second delimiter
Push "[E][options]"     ;[options]
                        ;  +number   : word number from start
                        ;  -number   : word number from end
