specifies a variable name.
The value that is returned is numeric.
Because the storage location of a variable can vary from one execution to
the next, the value that is returned by ADDR can vary. The ADDR function is
used mostly in combination with the PEEK and PEEKC functions and the CALL
POKE routine.
You cannot use the ADDR function on 64-bit platforms.
If you attempt to use it, SAS writes a message to the log stating that this
restriction applies. If you have legacy applications that use ADDR, change
the applications and use ADDRLONG instead. You can use ADDRLONG on both 32-bit
and 64-bit platforms.
The ADDR function returns the memory address
of a variable on a 32-bit platform. ADDRLONG returns the memory address
of a variable on 32-bit and 64-bit platforms.
Note: SAS recommends that you
use ADDRLONG instead of ADDR because ADDRLONG can be used on both 32-bit
and 64-bit platforms. ![[cautionend]](../../../../common/63294/HTML/default/images/cautend.gif)
The following example returns the address at which the
variable FIRST is stored:
data numlist;
first=3;
x=addr(first);
run;
