The following examples show how to use the IRA table:
•
Get the IRA code of the character ‘&’: the most significant nibble is 2, the least significant
nibble is 6, so the IRA code for the ‘&’ character is the hexadecimal value: 0x26.
•
Translate IRA code 0x6B into the corresponding character: the most significant nibble is
6, the least significant nibble is B, the cell at the crossing of column 6 and row B holds
the character: "k".
