Hello Mark,

No.  *N is simply a place-holder.  It doesn't mean NULL.  It allows you to
specify part of an element list (e.g., LOG(*N *N *SECLVL) or to handle
specifying a library while accepting the default for the first part of the
name (e.g., PGM(MYLIB/*N) ) or skip positional parameters (e.g., RUNQRY *N
CUSTMAST) or changing the library part of a qualified default value for a
command (e.g., NEWDFT('SRCFILE(*CURLIB/*N)') ) or to make it obvious that
values have been omitted (e.g., OVRDBF ??FILE(MYFILE) ??TOFILE(*N)
??MBR(*N) ) and so on ...

For the doubters among you:

      The value *N cannot be used to specify a null value because a null
       value cannot be passed to another program.

directly from the CL Programming manual when discussing the CALL command.

Simon Coulter.
