+With PSL's C++ style locals, you can say things like this:
+<pre>
+
+ for ( int i = 0 ; i < 10 ; i++ ) /* Do something */ ;
+
+</pre>
+In standard C++, the scope of the variable 'i' is from it's
+declaration to the end of the 'for' loop. However, Microsoft's
+Visual C++ uses an obsolete version of the C++ standard that
+allows the scope of 'i' to continue to the end of the block
+that contains the for loop. So:

+<H3>Hard Limits</H3>
Currently there are hard limits in many places - the number of
variables, the size of the program, the depth of nesting, etc.
These limits will gradually be removed as PSL is developed.
