In using a mouse, CLIK means press either mouse button once. The Window Clerk does not employ a CLIK-CLIK.  
 
All Window Clerk procedural sequences ('dialogues') are driven by screens which are composed of two component types:  
   l Command Buttons - like b_enter - that direct the Clerk to perform a specific, context-sensitive operation.  
   l Text Input Boxes - like curkey. - that provide the Clerk with operational information.  
 
CLIKing on a text input box produces the same result as [ Enter ] or [ Tab ] or b_enter.  
 
In all following procedure description presentations, when you see:  
 
   b_enter ........................................... CLIK on the current screen button labeled 'ENTER'  
.  
   curkey ........ Enter required text in the current screen box labeled 'Key'
