Sequences

Sequences are a format to describe series of numbers. They are used in the definition of storey heights. A simple sequence consists of a foot, a body and a head, in foot format; body *; head. Foot and head are optional, a body must be defined. The repeat character * marks the body and thereby determines which part of the sequence is repeated. A sequence can contain a maximum of one repeat character. The sequence 3; 4 *; 5 results in the series 3; 4; 4; ...; 4; 4; 5.

How often the body is repeated depends on the application. In the definition of storey heights, the body is repeated as many times as possible, so that the floors of the floor and the head can still be accommodated. The above sequence applied to a maximum height of 21m results in 5 storeys with heights 3, 4, 4, 4, 5. Bracket () can be used to group and allow finite repetitions.

Here are some examples: 4; (3; 4) *; 24; 3; 4; 3; 4; ...; 3; 4; 3; 4; 2 (5; 4) 2; 3 *; 55; 4; 5; 4; 3, 3, 3, ..., 3, 3, 5 5; ((4) 2; 3) *; 55; 4; 4; 3; 4; 4; 3; ...; 4; 4; 3; 4; 4; 3; 5
