Index store- Iw

- Instruction: Iw

- Parameter: none

- Return: none

- Description:

The index can temporarily be incremented or decremented. If the new index position is to be retained, this instruction stores it permanently. Storing the index may have unexpected transcription behaviors, so use the instruction with caution. This instruction is only executed if the condition state is true.

- Examples:

Text string: b

Braille string: 456

Condition: I+2 Tn "los" Iw

Description: Transcribes the letter "b" if the text "los" is present three positions ahead, in which case it stores the index. If the word in which the condition has been applied is the word "biblos", the letters "ib" will never be transcribed because the memorization of the index has allowed them to be skipped.
