Re: RNF0655 The item defined with the TEMPLATE keyword cannot be used in this context

I'm a bit surprised that %Len doesn't work on fixed length fields. Sure for Varying it has to be done at run time - but %Len( MyNumField ) is not dependant on content. I guess it simplifies the syntax checker.

I would not have expected either to work with a TEMPLATE.

When you specify a data structure as a TEMPLATE, there is no memory allocated for it. This is why it will not work with %LEN. The data structure does not actually exist in memory so %LEN cannot determine its length.

Perhaps %SIZE works because it looks at the definition of the structure and not the actual instance of it.

Just curious why an item defined with the TEMPLATE keyword is valid as %SIZE's argument but not for %LEN.

TIA
