To solve*some complex situations in PPL where the same procedure names and variables. Right now, when two forms are created in PPL with the same control names*and used within the same project it causes problems. In version 1.1 it won't be anymore.*It will probably appear in beta form in 1.06 so it can be stable and usable by 1.1.<pre>#namespace mylib</pre><pre>* global(a$);</pre><pre>* proc test
*** a$ = 10;
*** ShowMessage("MyLib.Test");
* end;</pre><pre>#endnamespace</pre><pre>#namespace mylib2</pre><pre>* global(a$);</pre><pre>* proc test
*** a$ = 20;
*** ShowMessage("MyLib2.Test");
* end;</pre><pre>#endnamespace</pre><pre>proc main</pre><pre>* ::mylib test;
* ::mylib2 test;</pre><pre>* ShowMessage(::mylib a$ + "," + ::mylib2 a$);* // Should display 10,20</pre><pre>end;</pre>

Let me know what you think.

Sound like a fantastic way of solving the problem of having to manualy change all the control references

Hi, here is an update on namespaces. The following code works perfectly.<pre>#namespace space1
proc test
* global(a$);
* a$ = 10;
* ShowMessage("Space1.Test");
end;
#endnamespace</pre><pre>#namespace space2
proc test
* global(a$);
* a$ += 20;
* ShowMessage("Space2.Test");
end;
#endnamespace</pre><pre>proc main
* a$ = 11;
* ::space1 test;
* ::space2 test;
* ShowMessage(::space1 a$ + "," + (::space2 a$ + a$));
end;</pre>

We still haven't worked on the object-oriented part. It might come with time.

Keep in mind that namespaces in 1.06 will be in beta stage.
