    • Apparatus for use in conjunction with a keyboard for operating a typesetter provides an indication when a justifiable line has been entered and continuously supplies a numerical indication of the line length remaining. The keyboard output code accesses incremental width information in a read-only-memory relative to the various characters selected, and this information is entered in an incremental width counter. The incremental width counter is counted down, and an accumulator counter is likewise counted down from an initial line length entry, for digitally outputting the line length remaining. In the event a character or word is deleted, the accumulator counter is accordingly counted upwards.
    • 与用于操作排版机的键盘一起使用的装置提供了当输入了合理线路时的指示,并且连续提供剩余线路长度的数字指示。 键盘输出代码相对于所选择的各种字符访问只读存储器中的增量宽度信息,并将该信息输入增量宽度计数器。 递增宽度计数器向下计数,并且累加器计数器同样从初始行长度条目向下计数,用于数字输出剩余的行长度。 在字符或字被删除的情况下,累加器计数器被相应地向上计数。
