ABSTRACT:
A tagged string is developed by setting the value of a current priority variable to the maximum priority level, selecting a shortest length string of the plurality the characters of which have not all been incorporated into the tagged string as the current string, selecting a character of the current string that is not found in the string that was processed for incorporation into the tagged string immediately prior to the current string, adding the selected character to the tagged string and setting the value of the priority indicator for the just added character to the value of the current priority value. Character selection, addition and priority setting are repeated until the characters of the current string are all incorporated into the tagged string. Thereafter, the value of the current priority variable is decreased. The process, except for the setting of the current priority level, is repeated until all strings have been incorporated into the tagged string. The message may also include one or more supplementary characters, in which case each character is tagged with a priority indicator and a supplement indicator. If so, characters are selected if they are not found in the immediately preceding processed string or if they are not in the longest string. The supplement indicator for each selected character is set if the selected character is not in all strings having a length greater than the current string when the current string is not the longest string.
