No.

If the value of a parameter has no influence over the content or appearance of a report then why would you have such a parameter in the first place?

Agree.  In CR2008 you can change parameters but Crystal will most likely run the report againn since it really doesn't know how the changed parameter will affect the report.
For instance even if you are only displaying that parameter the size of the field may ne affected.

What if there are several reports and by a mistake one of the parameters was selected wrong
Don't want to run the report again just want to rectify one parameter

What if a parameter changes once something contained in the report is known?

As we stated, crystal doesn't really know how the parameter is used. If it is part of record selection then obvious ly you have to rerun the report to select the new data.

If it is for display only then the report could just get an update.  But I don't think Crystal can do that.

We are trying to edit a text field based on a parameter
If it is true idoes one thing if it is false it does the other. We obviously don't know the answer to the parameter until the report is run becuase it gets a value from the details section

So you want to display
'ABC DEF GHI' if a vlaue is true
'JKL MNO PQR' if a value is false

What is the test?

You can use a formula like

If (YourField} = True then
   'ABC DEF GHI'
else
   'JKL MNO PQR'
