Teraspace access

Could anyone describe the proper way to access teraspace allocated with a 
procedure call to _C_TS_malloc() from within an ILE COBOL program?
 
I have a program with this in linkage:
 
01  ws-test-area    pic x(1000000).
 
 
Then it allocates 16MB with: 
 
Call procedure "_C_TS_malloc"                        
    using  by reference lk-tablsz-total-bytes        
    giving into         ws-tablsz-pointer            
    on exception Move "y" to flag-call-exception     
                 Move "_C_TS_malloc" to ws-subroutine
end-call.                                            
 
 
But if I do this, I get a pointer error:
 
Set address of ws-test-area
 to lk-tablsz-pointer.     
Move all "X" to ws-test-area.

Message . . . . :   Space offset X'00000000' or teraspace offset              
  X'00000080040880AF' is outside current limit for object @ZMIVP0037METZ3410  
  035241.                                                                     
Cause . . . . . :   You tried to operate outside the specified space, tried to
  operate on an unallocated page in teraspace, or tried to set the space      
  pointer outside the specified space. The object referred to is              
  @ZMIVP0037METZ3410  035241. The offset specified is X'00000000' for most    
  spaces, but X'00000080040880AF' for teraspace. The space class is X'07'. The
  secondary associated space number is X'0000'. The activation group mark is  
  X'00000000'. The heap space identifier is X'00000000'. The pointer to the   
  start of the implicit process space used for the allocation is              
  X'4000000000000000902A7180040880AF'. The space class designates the type of 
space as follows:                                                           
  00-primary associated space (includes space objects)                      
  01-secondary associated space                                             
  02-implicit process space for automatic storage                           
  03-implicit process space for static storage                              
  04-implicit process space for activation group-based heap storage         
  05-constant space                                                         
  06-space for handle-based heap storage                                    
  07-teraspace                                                              
  The object referenced and space class information is returned, whenever it
is available, for all space classes.  The other information is set only when
it applies to the returned space class value. Otherwise zero values are     
returned.                                                                   
 
 
 
Any ideas?
