initialize dynamic storage space

subroutine dsinit (w)
integer w

'Dsinit' initializes an area of storage in the common block CDSMEM
so that the routines 'dsget' and 'dsfree' can be used for dynamic
storage allocation.
The memory to be managed must be supplied by the user, by a
declaration of the form:
   DS_DECL (mem, MEMSIZE)

which turns into something similar to
   integer mem (MEMSIZE)
   common /cdsmem/ mem

The memory size must then be passed to 'dsinit' as its argument:
   call dsinit (MEMSIZE)

'Dsinit' sets up an available space list consisting of two blocks,
the first empty and the second containing all remaining memory.
The first word of memory (below the available space list) is set
to the total size of memory; this information is used only by the
dump routines 'dsdump' and 'dsdbiu'.

error
