Error generated when Instruction_Set doesn't have begin and end delimiter.

Error generated when Instruction_Set doesn't have begin and end delimiter.

Each instruction for a particular instruction set must be written withing Begin and End delimiter.
E.g. usage is 

begin INT_1       ;
   ADD  20        ;    
end   INT_1       ;

If this is not found, then the following error will be generated.

"VisualSim.kernel.util.IllegalActionException: Instruction_Set Initialize, 'end' Group Name cannot match 'begin' Group Name.
End Group Name: INT_1

Solution: Make sure to add begin and end in the Instruction_Set. For more information, read Instruction_Set documentation.
