Syntax

PEEKLONG(address<,length> )

Required Argument

address
specifies a character expression that is the memory address in binary.

Optional Argument

length
specifies the length of the numeric data.
Default:4
Range:1-4

Details

If you do not have access to the memory storage location that you are requesting, the PEEKLONG function returns an “Invalid argument” error.

Comparisons

The PEEKLONG function stores the contents of a memory address in a numeric variable. It assumes that the input address refers to an integer in memory.
The PEEKCLONG function stores the contents of a memory address in a character variable. It assumes that the input address refers to character data.

Example: Example

The following example copies the contents of the numeric variable Y to the numeric variable Z: 
data _null_;
   length y $4;
   y=put(1,IB4.);
   addry=addrlong(y);
   z=peeklong(addry,4);
   put z=;
run;
The output from the SAS log is: z=1
