Not so simple: 

1. -di varname- is perfectly legal and is equivalent to -di varname[1]-.


2. Clearly that is not equivalent to e.g. -list varname-. 

3. But if a constant were being held in a variable, -di varname- is
sufficient to see what it is. 

4. That is not especially good in terms of either style or efficiency,
but that is another story.

all I can see here is that at your 'problem 2' you try to -display- 
variables which won't work.
