pointers

Can someone explain the difference between a basing pointer in RPG and a
pointer in C?  Is there some other kind of pointer besides a basing
pointer in RPG?

Can someone explain how to do write the following C code in RPG:

void
main (){
char *buffer;

buffer = (char *) malloc (sizeof(char) * 1024);
return;
}

I know that I need to do something like:

D ptr           S       *
C                 alloc(e)      1024    ptr

but now how do I specify that ptr points to a buffer of type char?  Even
better:  how do I use alloc to allocate memory that looks like this:

D data          DS
D field                 100A

basically I want a 2-dimensional array that I can dynamically increase or
descrease.
