<div class="single"><h2>Description</h2>
<div><p>This function mimics what happens in the interpreter when an assignment to a global variable occurs, and can be useful if the name of the symbol is not known when the code is written.  If the value changes, then <a href="___Global__Release__Hook.html" title="">GlobalReleaseHook</a> and <a href="___Global__Assign__Hook.html" title="hook for assignment to global variables">GlobalAssignHook</a> are called appropriately.</p>
