MyProcedureWithOptionalParams(a.l = 42, *b.POINT = {8,15})

Now that we have optional, pre-initialized parameters it would be more
than useful to also be able to use this feature for structures IMHO:

Code: Select all

Procedure  MyProcedureWithOptionalParams(a.l = 42, *b.POINT = {8,15})
 ; *b\x = 8, *b\y = 15
EndProcedure

Hmm! That looks rather messy.

Personally I'd rather have:

Code: Select all

  Structure MyPoint
    x.l=1
    y.l=2
  EndStructure

and then?

Thats it!

Your idea would mean dynamic structures.

Remember, default values are only used if there is no value.

A structure is fixed, it does not change.
Currently a structure defaults all it's variables to 0.
So my idea make sense.

Your would not work without major changes to PB's handling of structures.

Ever tried to reference a variable in a structure and the variable did not exist?
Your idea would possibly have that issue all the time.

No, I think you misunderstood what I meant.

You can do x.l = 5 but you can't do x.POINT = {5,5} (same for arrays)

While there's a good way to fill in the values with macros now, there's
no way to use a pointer to a structure as an optional argument.
