Functions and CALL Routines |
Stores the contents of a memory address in a numeric variable
on 32-bit and 64-bit platforms.
PEEKLONG(address<,length>)
|
-
address
-
specifies a character constant, variable,
or expression that contains the binary pointer address.
-
length
-
is a numeric constant, variable, or expression
that specifies the length of the character data.
Default: |
4 on 32-bit computers;
8 on 64-bit computers. |
Range: |
1-4 on 32-bit computers;
1-8 on 64-bit computers. |
If you do not have access
to the memory storage location that you are requesting, the PEEKLONG function
returns an "Invalid argument" error.
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.
The following example returns the pointer address for 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
The following example, specific to the z/OS operating environment, returns
the pointer address for the numeric variable X.
data _null_;
x=peeklong(put(16,pib4.));
put x=hex8.;
run;
The output from the SAS log is: x=00FCFCB0
