You do however need this feature inside a CL-program (and the AS/400 does
it all the time): A command can 'call' a CL-program with maybe not a
varying number of parameters but with 'null'-parameters. You can cope
with this by monitoring for the genereted escape each time you refer to
parameters that are not required.
