The machine-readable format of the single-byte to single-byte conversion table is a file containing a single 256-byte record. This allows for 256 single-byte output values. Each character in the table corresponds to one input code point, X'00' through X'FF'. The byte value of the character that is found in the location corresponding to the input code point value is the output code point.
In the example shown in Figure 69, to find the output code point for the input code point X'53', we convert it to a decimal value of 83 and look at offset 83 in the record. (The first position is offset 0.) The value that we find at offset 83 is the corresponding output code point. In this example it is X'67'.
These tables are the standard distribution and storage format of CDRA.
