Does a logical EQUIVALENCE between the bits of two data items. 
	 
  
 
	 Syntax:
 
		 
		call "CBL_EQ" using    source
                       target
              by value length
 
	 Parameters:
 
		 
		 
		
 
			  
			  
			  
			  
				 
				  |  | Using call prototype (see 
					 Key) | Picture | 
 
			 
 
			  
				 
				  | source | cblt-x1-compx | Any data item. | 
 
				 
				  | target | cblt-x1-compx | Any data item. | 
 
				 
				  | length | cblt-os-size | Numeric literal pic x(4) comp-5
					  or 
					  pic x(8) comp-5 (64-bit native programs only) 
					  | 
 
			 
 
		  
 
 
	 On Entry:
 
		 
		 
		
 
			  
			  
			  
				 
				  | source | One of the data items to EQUIVALENCE. | 
 
				 
				  | target | The other data item to EQUIVALENCE. | 
 
				 
				  | length | The number of bytes of 
					 source and 
					 target to EQUIVALENCE. Positions in 
					 target beyond this 
					 length are unchanged. | 
 
			 
 
		  
 
 
	 
Comments:
The routine starts at the left-hand end of source and target and EQUIVALENCEs the bits together, storing the result in target. The truth table for this is:
