# Supported Syntax for Model Parameter Manager

The Model Parameter Manager supports simple text files ( .txt) as model parameter files.

The Model Parameter Manager allows text files that conform to the model parameter file format that other VeriStand features support.

One limitation of using model parameter text files is that the manager imports and sets the result of the expression rather than the expression itself. The following parameter definitions demonstrate this limitation.

a 10
b a * 2

In this example, the Model Parameter Manager sets the value of b to 20, not a * 2. Changes to the value of a do not affect b because the original expression is no longer valid.
