 
 If a command is not found by MCR either in its internal  tables  or  as  an
 external task installed with the name ...XYZ, the entire MCR command buffer
 is passed on to a catchall task ...CA.   CCL is a catchall task  which  has
 two parts.  The command is first scanned to see if it  corresponds  to  any
 internal CCL commands.  If a command is found it is  interpreted  and  sent
 to MCR.  If the command is not found,  an  attempt is  made  to  decode the
 command  using  either  a  command  procedure  file  on  the   user's   UIC
 (SY:USERCCL.CCL) or a system command procedure file (LB:[1,5]SYSCCL.CCL).

 HELP in using CCL may be obtained by typing the following:

	HELP CCL BUILT_IN	Show commands built into CCL.
	HELP CCL SYSTEM		Show commands in our system CCL file.

 The full document describing how to build and use CCL commands may be
 obtained by either of the following commands:

	HELP CCL DOCUMENT		Type the document on your terminal
		or
	PRINT LB:[1,2]CCLDOC.HLP	Print the document on the lineprinter
