7.11 change_end

• type: action command.
• function: change the ending point in a lattice
• sequence: must precede run_setup.
• Command syntax, including use of equations and subcommands, is discussed in 7.2.

• element_name — Name of the element where the lattice will end, which implies removing all elements downstream of the named element. If the element occurs more than once, the first instance is used, unless element_occurence is given. The named element will be the last element in the lattice.
• element_occurence — Occurrence number of the element to use. By default, uses the last occurrence.
• delta_position — The number of elements before (if negative) or after (if positive) by which to offset the end position.
