### 18.4.1. Adding and Modifying User Parameters

There is a `USER:` object in command language for automatically passing user parameters to the solver (for access by User Fortran routines). Any parameter may be defined inside this object by simply adding statements of the form `name = value` within the `USER:` object.

The `USER:` object and parameters can be added to a CFX-Solver input file using `cfx5cmds`. For details, see Editing the Command Language (CCL) File in the CFX-Solver Manager User's Guide. Once user parameters have been entered into the problem definition, they can also be seen and modified in the Command File editor.
