Global variable limitations

I don't know of any limitations.

When discussing global variables, please make it clear whether you are referring to globally declared variables or Global Variables of the client terminal.

Good point.  Sorry.  I'm asking about the Global Variables of the client terminal.

I ran this in a script

  for(int x=0; x<10000; x++)
     GlobalVariableSet("GV"+IntegerToString(x),x);
  GlobalVariablesFlush();
  Print("Total GVs=",GlobalVariablesTotal());

It quite surprised me that it took 20 seconds to run the script, quite slow really.

Anyway, I got to over 120,000 GVs
