No problem.

Oh man.  With syntax you can demystify those in any number
of ways.  Just a matter of what you are wanting.  You can
always add sugar:

    /memreserve_block/    10000000 00002000;
    /memreserve_range/    10000000 10001fff;

    /memreserve/    10000000 /for/     2000;        //  or /size/ ?
    /memreserve/    10000000 /through/ 10001fff;

    /memreserve/    10000000 00002000;
    /memreserve/   [10000000, 10001fff];     // or [10000000, 10002000)?

Stuff like that maybe?
