[Jprogramming] timer in j701?

[David Mitchell]

You are welcome, Ian.

I am a bit curious about J support for dylibs.  I currently do not have any way 
to try it myself, but the J DLL documentation does say:

J can call procedures that are compiled in a shared library file. In Windows 
these files are called DLLs (dynamic link libraries) and have a .dll extension. 
In Linux they are called shared libraries or shared objects and have a .so 
extension. In Mac they are called dynamic libraries and have a .dylib extension. 
The term DLL is used here for all platforms. A procedure in a DLL is called by 
its name and filename.

It is true that there may not be dylib functionality for Darwin that matches 
what Windows has for timer usage, but I saw a function 
"dispatch_source_set_timer" in the GCD reference from Apple that seemed as if it 
might be a start.
