 ; Revision History
 ;------------------
+; 16 September 2004 by David "BAILOPAN" Anderson
+;     Implemented a compile time toggleable debug hook on OP_CALL and OP_RET.
+;     NOTE: JIT has not had debug hooks since 1999.
+;  8 September 2004 by David "BAILOPAN" Anderson
+;     Changed OP_LINE call to be compile-time toggle-able between compiling
+;	  line ops or not.
 ; 29 June 2004  by G.W.M. Vissers
 ;	Translated the thing into NASM. The actual generation of the code is 
 ;	put into the data section because the code modifies itself whereas the
