Union flag- Xu

- Instruction: Xu - Parameter: none - Return: none - Description: This is a complementary flag to the "Iu" instruction (Unable index with flag). The "Iu" instruction is useful for removing the space or spaces between words. The code with flag "Xu" always follows a code with flag "Iu", and between the two codes any space will be removed. - Examples: Text string: to Braille string: 2345 135 Condition: Iu Text string: be Braille string: 12 15 Condition: Xu Text string: have Braille string: 125 1 1236 15 Condition: Xu Description: If "to be" or "to have" is present, the braille processor will combine the two words into "tobe" and "tohave". So, if a word with the condition "Iu" is followed by a word with the flag "Xu", the transcription processor removes the space between the two words.
