The general problem of conveying a particular meaning in a message so that the meaning is most understandable when an abridged version of the message is displayed is solved by supplying as the message a "tagged" string in which all characters in the unabridged version of the string are tagged with respective priority indicators each having a value indicating a particular priority level. In a station set, an abridged version of the string for a particular priority level is determined by selecting all characters from the received, unabridged version having a priority indicator value equal to or greater than that particular priority level. A priority level is selected such that the corresponding abridged string fits within the available display length. In accordance with a feature of the invention, the message may further include one or more supplementary characters each also tagged with a priority indicator, and the abridged version of the string for a particular priority level includes not only the characters selected as aforesaid, but also any supplementary characters whose priority indicator has that particular value. This, advantageously, allows the version of the string for each priority level to include characters that a) do not even appear in the unabridged version of the string, or b) are not displayed as part of some abridged, but longer version(s) of the message, even though they appear in the unabridged version.
