### 3.1.3. Syntax of CFX Resource Configuration Files

ANSYS CFX resource configuration files should consist only of:

- Lines beginning with # (which are comments).

- Variable assignments such as: `CFX5EDITOR="textedit"`

The right hand side of an assignment may include references to previously assigned variables by prefixing the variable name with `$`; for example,

    CFX5BROWSER="$CFX5EDITOR"

Note: In previous releases of ANSYS CFX, these files could contain arbitrary Bourne shell commands. These are no longer supported.

#### 3.1.3.1. Resource Names

ANSYS CFX software makes use of variable names that start with the following strings:

- `CFDS_`

- `CFX_`

- `CFX4`

- `CFX5`

- `CUE_`

You must not set any variable of your own with a name beginning with these letters.
