Computers use internal binary numbers to represent both text and numeric data.
Among the various computer manufacturers, two standard code sets have emerged that specify the relationship between an internal binary number and the character that it represents. The only exception is the IBM PC family of computers. If the file is not found, or if the program cannot load the file, the default character translation tables embedded in the program code are used. You can later revert to the default table by copying the file back to xlat.tbl. CTI is also an authorized IBM Business Partner, Hewlett Packard Business Partner and 3COM Business Partner.
