PEEKLONG(address<,length>) |
specifies a character constant, variable, or expression that contains the binary pointer address.
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. |
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.
Examples |
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
