LOADBTM - Switch a batch file's mode

 Purpose:    Switch a batch file to or from BTM mode. 
             
 Format:     LOADBTM [ON | OFF] 
 

 Usage 

 CMD.EXE recognizes two kinds of batch files: .BAT or .CMD, and .BTM. 
  Batch files executing in BTM mode run two to ten times faster than in 
 BAT or CMD mode.  Batch files automatically start in the mode indicated 
 by their extension. 

 The LOADBTM command turns BTM mode on and off.  It can be used to switch 
 modes in either a .BAT / .CMD, or .BTM file.  If you use LOADBTM with no 
 argument, it will display the current batch mode:  LOADBTM ON or LOADBTM 
 OFF. 

 Using LOADBTM to repeatedly switch modes within a batch file is not 
 efficient.  In most cases the speed gained by running some parts of the 
 file in BTM mode will be more than offset by the speed lost through 
 repeated loading of the file each time BTM mode is invoked. 

 LOADBTM can only be used within a batch file.  It is most often used to 
 convert a .BAT or .CMD file to BTM mode without changing its extension.
