Reads integer binary (fixed-point) values in Intel and DEC
formats.
-
w
-
specifies the width of the input field.
-
d
-
specifies the power of 10 by which to divide
the value. This argument is optional.
The IBRw.d informat reads integer binary (fixed-point) values,
including
negative values that are represented in two's complement notation. IBRw.d reads integer binary values
that are generated by and for Intel and DEC platforms. Use IBRw.d to read integer binary data
from Intel or DEC environments in other operating environments. The IBRw.d informat in SAS code allows
for a portable implementation for reading the data in any operating environment.
Note: Different operating environments store integer
binary values in different ways. This concept is called byte ordering. For
a detailed discussion about byte ordering, see
Byte Ordering for Integer Binary Data on Big Endian and Little Endian Platforms.

The
IBw.d and PIBw.d
informats are used to read native format integers. (Native format allows you
to read and write values that are created in the same operating environment.)
The IBRw.d and PIBRw.d informats are used to read
little endian integers in any operating environment.
On Intel and DEC operating environments, the IBw.d and
IBRw.d informats are equivalent.
To view a table that shows the type of informat to use
with big endian and little endian integers, see
SAS Informats and Byte Ordering.

in several programming languages, see
Integer Binary Notation and Programming Languages.
You can use the INPUT statement and specify the IBR
informat. However, in these examples we use the informat with the INPUT function,
where binary input values are described using a hexadecimal literal.
x=input('0100'x,ibr2.);
y=input('0001'x,ibr2.);
