Syntax

ADDRLONG(variable)

Arguments

variable: specifies the variable name that points to the memory address.

Details

The return value is a character variable that contains the binary representation of the pointer. To display this value, use the $HEXw. format to convert the binary value to its hexadecimal equivalent.

Note: If you used the ADDR function and defined an instance of the pointer as numeric by using a LENGTH statement in your program, substituting ADDR for ADDRLONG will fail because ADDRLONG requires a character argument. [cautionend]

Examples

The following example returns the pointer address for the variable ITEM, and formats the value.

data characterlist;
   item=6345;
   x=addrlong(item);
   put x $hex16.;
run;

The following line is written to the SAS log:
