AIFSCGET, item #3039 returns the amount of physical memory in units
of 2048 byte pages (not 4096 byte pages, BTW).
You used to have to purchase the AIF:OS manual to find the calling
sequence/information for this intrinsic.

Other techniques exist, certainly.

For example:

    extern void get_memsize (uint32 *num_2kpages);    /* internal OS routine */


    int32 get_memsize_mbs ()    /* returns # of megabytes of memory */
       {

       uint32                   /* *everyone* uses int32/uint32, don't they?! */
          num_2kpages = 0;


       GETPRIVMODE ();          /* get_memsize requires priv mode */

       get_memsize (&num_2kpages);

       return (num_2kpages / 512);   /* return # of megabytes, rounded down */
       }

Prep program with CAP=PM.
