Passing Parameters to a View via URL

I need to pass a variable from a "passive screen" to a View screen. The data is to be used in the evnt that a user wants to "ADD" a record via the view screen

The value that needs to be passed is not a constant (like 1234) - the value will not be known so the openurl can not have a constant passed through.

How do I use the openurl command with a variable to be passed - not a constant.

Here is the instruction on passing numeric constants (which is clear..)

There is no example of this instruction with the use of a variable in the place of the constant.
