_CMDPROC

_CMDPROC is the name of the current command processor.  Each JP Software 
command processor returns a different value, as follows: 

        Product                         Returns 
                                        
        4DOS                            "4DOS" 
        CMD.EXE                         "CMD.EXE" 
        4NT                             "4NT" 
        Take Command/16                 "TCMD" 
        Take Command/32                 "TCMD32" 
        Take Command for OS/2           "TCMDOS2" 
 

 This variable is useful if you have batch files running in more than one 
 environment, and need to take different actions depending on the 
 underlying command processor.  If you also need to determine the 
 operating system, see _DOS.
