The best example that I have of this is contained in the source code to
the public domain program SYNONYM3.  Basically what is done is that the
command line buffer in the CCP is stuffed with the command line to be
executed, the proper length and character position pointer is set and 
control is transferred to the CCP.  This does not work with ZCPR, and can
only be used if the program you are chaining from does not overwrite the
CCP.  Get the source to SYNONYM3 from a BBS or your local user group and
have fun.
