Unformatted text preview: binary notation T = 1110 0011 in EBCDIC-binary notation So the EBCDIC coding for the word BIT in binary notation will be 11000010/B 11001001/I 11100011/T 3 bytes will be required for this representation because each letter requires 1 byte (or 8 bits). Example 4.4. Write the EBCDIC coding for the word ZONE (use hexadecimal notation). How many bytes will be required for this representation? Solution: Z = E9 in EBCDIC hexadecimal notation O = D6 in EBCDIC hexadecimal notation N = D5 in EBCDIC hexadecimal notation E = C5 in EBCDIC hexadecimal notation So the EBCDIC coding for the word ZONE in hexadecimal notation will be E9/Z D6/O D5/N C5/E Each hexadecimal digit requires 4 bits and there are altogether 8 hexadecimal digits. So in all 8 x 4 = 32 bits or 4 bytes (8 bits = 1 byte) will be required for this representation. . > We may also write directly that since each letter requires 1 byte for its representation in EBCDIC and there are 4 letters in the word ZONE, 4 bytes will be required for this representation. Example 4.5. Write the EBCDIC zoned-decimal coding for the value +256 (use hexadecimal). How many bytes will be required for this representation? Solution: +256 = F2F5C6 in EBCDIC Each hexadecimal digit requires 4 bits and there are altogether 6 hexadecimal digits. So in all 6 x 4 = 24 bits or 3 bytes (8 bits = 1 byte) will be required for this representation. We may also write directly that since each digit requires 1 byte for its representation in the EBCDIC zoned decimal coding and there are 3 digits in the given number, 3 bytes will be required for this representation. Example 4.6. Write -128 as packed decimal number (use hexadecimal). required for this representation? Solution: How many bytes will be -128 = F1F2D8 in EBCDIC = 128D in packed format Each hexadecimal digit requires 4 bits and there are altogether 4 hexadecimal digits. So in all 4 x 4 = 16 bits or 2 bytes (1 byte = 8 bits) will be required for this representation. ASCII Another computer code that is very widely used is the American Standard Code for Information Interchange (ASCII). ASCII has been adopted by sever...
