Re: %DecPos on a template variable

An idea - there is no memory allocated to a template. You have 2 
messages saying that neither the structure nor its subfield can be used, 
since they are in a DS defined with TEMPLATE.

I have a feeling that %len would also fail when used against a templated 
item - does it?

It seems we SHOULD be able to get attributes of variables that were 
defined with TEMPLATE, doesn't it? Or am I expecting more than is 
practical? Is this possible with templates in C/C++?

Unlike %len, which returns the length of a field which can fluctuate if it's a varchar, I don't see how %decpos could be anything but the decimal precision of the field at compile time.  Am I missing something here?  We're at IBM i 7.1.

I wanted to get the %decpos of the field that the amount fields are being defined like, instead of arbitrarily picking one (what if one goes away with a future change, then this procedure call will have to change as well).
