First of all, you should understand that dual dimensioning is an illusion,
a 
trick performed by Pro/e at the time the dimension is created or placed. 
Whichever one is NOT your default system of units (usually, but not 
necessarily, your secondary units) is the result of a calculation and
placed 
in the drawing according to formatting definition in your DTL file. IOW,
if 
you select the dimension and RMB 'Properties', go to the Dimension Text
tab, 
you'll see nothing special about the format (still @[EMAIL PROTECTED]
) and the Name of the

dimension parameter still a single name like 'd61'. The secondary
dimension 
is an operation, not a parameter. So, it will not be possible to show it 
with &parameter_name because there is no special parameter for dual 
dimensioning or for the secondary dimension. In fact, you'll notice that 
when you do 'Info>Switch Dimensions', the Primary (parametric) part of the

dimension shows the parameter name but the secondary part remains literal 
text. So, there is only one set of tolerances, those in your default
system 
of units. Anything else is the result of a calculation based on a
conversion 
factor. You could, I guess, set this up with Relations as 
TOL1=linear_tol_0_00/25.4, then display this as [x.xx]=&TOL1.

I'm all for using all the power of parametrics wherever possible and 
appropriate. But the standard, stable, static info in a format? Shouldn't
we 
be reserving the use of parametrics for design and detailing elements that

vary constantly?
