@anatolyg Combining with other short opcodes that operate on AL like LODSB, AAM, AAD, INT 10/21H, it could be golfy. For example, this code char bx[] = "qwertyuiop"; al = bx[ al % 10 ]; "get an arbitary character in a string using the rightmost digit in accumulator as index" would be 3 bytes AAM / XLAT. Used here.
