Does ATS\_DYNLOADFLAG 0 in a dats file mean automatically init the file if compiled, or just prevent compile errors if not dyloaded, meaning do not do this if there are values to init?

Normally, ATS compiler generates a function for each file  
that must be called before values and functions defined in  
the file can be used.

If ATS\_DYNLOADFLAG is set to 0, then such a function is not  
generated and the programmer needs to take care of issue of initialization  
on their own. Just like in C.On Tue, Dec 29, 2015 at 1:44 PM, Mike Jones [proc...@gmail.com](mailto:proc...@gmail.com) wrote:
