creating a boolean parameter 1

[iwm]

How do you create a parameter that uses a boolean value?
I am currently using Crystal Reports version 9.
Your assistance in this matter is greatly appreciated.

Right click the Prameters heading the the Field Explorer and select New and change the data type to a boolean.

To use the parameter, you might set the default values to false being the first (should be the default), and then in the record selection formula use something like:

if not({?MyBooleanParm}) then //means it's false
{table.field}=false
else
{table.field}=true

-k

synapsevampire,
What if a table.field doesn't exist for this particular parameter? Is it possible to create a boolean parameter without referencing a table.field.

Sure, just go ahead and create it.

What are you intending to do with it?

You can certainly use it for suppression, etc.
