call "CBL_EQ" using    source
                       target
              by value length 
               	 | 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)  |  
                              				
                           
| 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. | 
| target | The result. | 
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:
