etGenerateObserverCount</B>(boolean&nbsp;generateObserverCount)</PRE>
<DL>
<DD>Turn on or off generation of code with callbacks to
 track the count of executed instructions.
 Currently only affects JVM byte code generation: this slows down the
 generated code, but code generated without the callbacks will not
 be counted toward instruction thresholds. Rhino's interpretive
 mode does instruction counting without inserting callbacks, so
 there is no requirement to compile code differently.
