If the right +parameter is not as wide as required, white space is added at the right; +if it is too wide, its paragraphs are broken (Section {@NumberOf break}) +so that it fits. A @@OneCol operation is included in the effect of @@Wide, +since it does not make sense for an object of fixed width to have two column +marks. +@PP +high.sym @Index { @@High symbol } +The @@High symbol similarly ensures that its result is of a given height, +by adding white space at the bottom. In this case it is an error for the +right parameter to be too large. A @@OneRow operation is included. +@End @Section |
