COMB.DLL is a DLL that replaces OVLOOPS.DLL and CHOICE.DLL.  

The functions in COMB.DLL are registered exactly as they are in 
CHOICE.OVD and  OVLOOPS.OVD found in the ObjectVision SAMPLE subdirectory.

The syntax for registering the OVLOOPS functions is:

@REGISTER("@REGISTER_OVLOOPS","In","","COMB.DLL","SelfRegister",1)
@REGISTER_OVLOOPS

The @REGISTER_OVLOOPS will not be recognized by ObjectVision until the 
@REGISTER command is executed.  For this reason, if these commands are done 
on the OPEN event of the stack, it will be necessary to "comment out" (using 
a single appostrophe as the first character of the line) the 
@REGISTER_OVLOOPS command, save the application, and reopen it, activating 
the @REGISTER to register @REGISTER_OVLOOPS.  At this time you will be 
able to remove the appostrophe in front of the @REGISTER_OVLOOPS command.  
Again, in order to execute @REGISTER_OVLOOPS, you will need to save and 
reopen ObjectVision again.

The syntax for registering the CHOICE functions is:

@REGISTER("@CHOICE","FACCF","Condition,TrueString,
                              FalseString","COMB.DLL","ChooseString",0)

There is an additional function in COMB.DLL called @MessageBeep. This 
function simply rings the standard Windows beep function.
