Question about _MEM blocks and arrays

[FCS_coder]

OK, now that I have the 32/64 bit thing handled I have another question I've been chewing on...can I use _MEM blocks to hold dynamic arrays?  Looking at the wiki, I see how I can use _OFFSET to manipulate bytes/words in a block of memory, but is there a way to use arrays instead?  That would make the access easier: a simple index rather than an opaque location pointer into a block.  But it looks like while I could put a string into a _MEM pointer, I can't do the same with an array
