Language support PL/I. PL/I uses the PICTURE attribute to declare zoned decimal data with a signed overpunch. Each character in a numeric picture except V, which indicates the position of the assumed decimal point, represents a digit.

zoned decimal data, while others must use software to emulate the computations. For example, the IBM mainframe has an Add Pack instruction to add packed decimal data, but the Intel-based platforms have no such instruction and must convert the decimal data into some other format. Languages Supporting Packed Decimal and Zoned Decimal Data If you a creating a flat file that is to be ftp’ed to the mainframe, its a bit more work. A S9(6)V99 field is an 8 character string that holds a number with 2 decimal places and a zoned sign at the beginning or end of the number. If the number you are storing is positive, you don’t need to worry about the zoned sign. Working with Packed Decimal (Comp-3) Fields, Packed Numeric and Zoned Decimal Fields Often mainframe reports contain zoned decimal and packed decimal fields which are either unreadable or incorrect when converted directly to ASCII. Using TextPipe's Mainframe Copybook Wizard, you can paste in a copybook with your field names, Zoned decimal equivalent in Syncsort for DB2 decimal datatyp by Prasanna G » Thu Apr 16, 2015 7:46 am 5 Replies 1705 Views Last post by BillyBoyo Thu Apr 16, 2015 12:29 pm To convert Julian date in packed format to Gregorian by kimir » Wed Mar 14, 2012 3:23 pm 1 Replies 5994 Views Last post by bodatrinadh Wed Mar 14, 2012 5:57 pm Some implementations, for example IBM mainframe systems, support zoned decimal numeric representations.

Zoned Decimal (normal numbers) - each byte contains 1 decimal digit. The upper four bits should always contain HEX F, except possibly the least most significant byte where the upper 4 bits may contain the sign and the lower 4 bits a digit.

Using TextPipe's Mainframe Copybook Wizard, you can paste in a copybook with your field names, 2001-05-02 If a zoned decimal is Signed and the SIGN clause is not specified (nor the NUMERIC SIGN special-names clause is specified), then the sign is stored in the second part of the last byte together with the last digit, using "C" for postive values or "D" for negative values. Some implementations, for example IBM mainframe systems, support zoned decimal numeric representations. Each decimal digit is stored in one byte, with the lower four bits encoding the digit in BCD form.

The last byte contains the number's sign as well as the last digit. Zoned decimal data produces a printable representation. Nibble: specifies 1/2 of a byte. 2012-03-27 · In most of the scenarios, your input file has data either in Packed decimal (COMP-3) format or Binary (COMP) format which is not in readable format. To change this to readable format, you need to convert these numbers into ZONED Decimal (ZD) format. This can be accomplished using SORT.

The TO=ZD parameter converts the 4 byte binary fields to its equivalent zoned decimal value in the output file. By default, a 4-byte BI value produces a 10-byte ZD value,if you wish to modify this and give a custom value, we can use the LENGTH option along with TO OUTREC FIELDS=5,4,BI,TO=ZD,LENGTH=6

The last four bits of a number are reserved for a sign. Positive are binary 1010, 1100 1110 and 1111. Negative is 1011 and 1101. For example the number -354 woud be stored as 0x354d, 7251 would be stored 0x07251c.

2017-02-14 · FIELDS – The major control field begins on byte 7025 of each record, is 4 bytes long, contains zoned decimal data (FORMAT=ZD), and is to be sorted in ascending sequence. The second control field begins on byte 5048, is 8 bytes long, has the same data format as the first field, and is also to be sorted in ascending order.

To change this to readable format, you need to convert these numbers into ZONED Decimal (ZD) format. This can be accomplished using SORT. If a zoned decimal is Signed and the SIGN clause is not specified (nor the NUMERIC SIGN special-names clause is specified), then the sign is stored in the second part of the last byte together with the last digit, using "C" for postive values or "D" for negative values.
