PTRLONGADD(pointer<,amount>)

pointer

is a character constant, variable, or expression that specifies the pointer address.

amount

is a numeric constant, variable, or expression that specifies the amount to add to the address.

The PTRLONGADD function performs pointer arithmetic and returns a pointer address as a character string.

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

data _null_;
   x='ABCDE';
   y=ptrlongadd(addrlong(x),2);
   z=peekclong(y,1);
   put z=;
run;

The output from the SAS log is: z=C
