RE: Allocate field with options(*nopass :*omit)

I'm not familiar with the restrictions of %addr with a Const parameter,
but in order to simulate a default value...

Have the field you're going to use in your D-specs and make it Based.
Set its pointer to the parameter if it was passed, otherwise set the
pointer to a pre-defined constant?

I guess generally I simply move the data into an intermediate field, but
the fields are never very big when I have to deal with this kind of
situation.

Right, If Lim is looking for "default parameter values" like you have in
C++, then Lim is out of luck.
Default parameter values would be wonderful, but they aint't there.

Unfortunately what you want to do can't really be done. Given that your
parameter is a constant you can only have a local variable with a
default value (as has already been suggested). If you changed your
parameter by removing the "const" keyword you could do something like
this:

     P test            B

     D test            pi
     D  piParm1                      10a   options(*nopass)

     D pi              s                   like(piParm1) based(piPtr)
     D piPtr           s               *   inz(*null)

     C                   if        %parms() >= 1
     C                   eval      piPtr = %addr(piParm1)
     C                   else
     C                   alloc     %size(piParm1)piPtr
     C                   endif

     C                   if        pi = *blank
     C*                    .... Do something
     C                   else
     C*                    .... Do something else
     C                   endif

     C                   if        %parms() < 1
     C                   dealloc(n)              piPtr
     C                   endif

     p test            E

However it's hardly worth the effort. Better to use the local variable.

Use below as example:

If piParm1 is not passed, I normally have to create a temporary variable
(myParm1) to use it later in the procedure.
p test            B
d                 pi
d  piParm1                      10a   options(*nopass) const

d myParm1         s                   like(piParm1)

c                   if        %parms() >= 1
c                   eval      myParm1 = piParm1
c                   endif

c         if        myParm1 = *blank
C    .... Do something
C   else
C                     .... Do something else
C                   endif

p test            E

I would prefer to be able to do something like below
p test            B
d                 pi
d  piParm1                      10a   options(*nopass) const

c                   if        %parms() >= 1
c                   alloc     %size(piParm1) piParm1

c                   endif

c         if        piParm1 = *blank
C    .... Do something
C   else
C                     .... Do something else
C                   endif

p test            E

Not sure what you're looking for. Procedures don't allocate memory for
parameters that are passed in. What are you trying to accomplish?

  Is there a way for procedure to allocate memory for entry parm field
  that is not being pass in by the caller?

  example:
  d testPrc         pr
  d  piParm1                      10a   options(*nopass) const
