Runtime Error Codes

Runtime error codes and messages used by the runtime library.

Description
	Freebasic returns the following runtime error codes:
		Ŀ
		  0 No error                     
		  1 Illegal function call        
		  2 File not found signal        
		  3 File I/O error               
		  4 Out of memory                
		  5 Illegal resume               
		  6 Out of bounds array access   
		  7 Null Pointer Access          
		  8 No privileges                
		  9 interrupted signal           
		 10 illegal instruction signal   
		 11 floating point error signal  
		 12 segmentation violation signal
		 13 Termination request signal   
		 14 abnormal termination signal  
		 15 quit request signal          
		 16 return without gosub         
		 17 end of file                  
		

	No user error code range is defined. If KeyPgErrorError is used to set an error 
	code it is wise to use high values to avoid collisions with the list of 
	built-in error codes. (This built-in list may be expanded later.)
