PEEKCLONG Function

Stores the contents of a memory address in a character variable on 32-bit and 64-bit platforms

Category: Special

See: PEEKCLONG Function in the documentation for your operating environment.

Syntax

PEEKCLONG ( address <, length >)

Arguments

address

specifies a character string that is the pointer address.

length

specifies the length of the character data.
Default: 8
Range: 1 to 32,767

Details

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

Comparisons

The PEEKCLONG function stores the contents of a memory address in a character variable.

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.

Examples

Example 1: Example for a 32-bit Platform

The following example returns the pointer address for the character variable Z.

 data _null_;     x='ABCDE';     y=addrlong(x);     z=peekclong(y,2);     put z=;  run;

The output from the SAS log is: z=AB

Example 2: Example for a 64-bit Platform

The following example, specific to the z/OS operating environment, returns the pointer address for the character variable Y.

 data _null_;     length y ;     x220addr=put(220x,pib4.);     ascb=peeklong(x220addr);     ascbaddr=put(ascb,pib4.);     y=peekclong(ascbaddr);  run;

The output from the SAS log is: y= ' ASCB '
