It is just the same as any other BASED() structure.  No memory is 
allocated by the compiler for myDS.  There's nothing special about 
TEMPLATE in this case, except that it is meant to be obvious to other 
programmers that the DS is not meant to be used directly, only as a 
basis for LIKE() defining.

At V6R1, there is a new keyword which lets you define a data structure 
as a template.  One of the benefits over the workaround method above is 
that you can use the INZ() keyword on the DS subfields.
