When
processing in a
z/OS environment, you should also be aware of the
way that SAS stores integers. Like other numeric values, SAS maintains
integer variables in 8-byte floating-point (real binary) representation.
But under
z/OS, outside of SAS, integer values are typically represented
as 4-byte (fixed point) binary values using two's complement notation.
SAS can read and write these values using informats and formats, but
it does not process them internally in this form. SAS uses floating-point
representation internally.
You can use the IB
w.d informat
and format to read and write the binary integer values used under
z/OS. Each integer uses 4 bytes (32 bits) of storage space. Thus,
the range of values that can be represented is from
−2,147,483,648 to 2,147,483,647.
