Unable index with flag- Iu

- Instruction: Iu

- Parameter: none

- Return: none

- Description:

This instruction checks if there are conditions to reset the index, in order to eliminate spaces between words. It is used in conjunction with the "Xu" flag. This instruction is executed only if the condition status is true.

- Examples:

Text string: be

Braille string: 12 15

Condition: Xu

Text string: to

Braille string: 2345 135

Condition: Iu


When "to" is followed by "be", the space between the two words is removed, i.e. the index is merged with the following code that has the merge flag "Xu".
