ZDw.d

Category:

Numeric

Syntax Description

w

specifies the width of the input field.

Default:	1
Range:	1-32

d

optionally specifies the power of 10 by which to divide the value.

Range:

1-31

Details

The ZDw.d informat reads zoned decimal data in which every digit requires one byte and in which the last byte contains the value's sign along with the last digit.

Note:   Different operating environments store zoned decimal values in different ways. However, ZDw.d reads zoned decimal values with consistent results if the values are created in the same type of operating environment that you use to run SAS.  

You can enter positive values in zoned decimal format from a terminal. Some keying devices enable you to enter negative values by overstriking the last digit with a minus sign.

Comparisons

• Like the w.d informat, the ZDw.d informat reads data in which every digit requires one byte. Use ZDVw.d or ZDw.d to read zoned decimal data in which the last byte contains the last digit and the sign.

• The ZDw.d informat functions like the ZDVw.d informat with one exception: ZDVw.d validates the input string and disallows invalid data.

• The following table compares the zoned decimal informat with notation in several programming languages:

  Language	Zoned Decimal Notation
  SAS	ZD3.
  PL/I	PICTURE'99T'
  COBOL	DISPLAY PIC S 999
  IBM 370 assembler	ZL3

  
  

Examples

input @1 x zd4.; 

Data Lines*	Results
----+----1
F0F1F2C8	128
*The data line contains a hexadecimal representation of a binary number that is stored in zoned decimal format on an IBM mainframe computer system. Each byte occupies one column of the input field.
