Note that all variable names are case–sensitive. Enter the appropriate changes
to the variable, then pick the
button. When you do, the keyboard
disappears and the changed variable appears in the Environment panel.
NOTE: An edited variable may not become effective immediately; usually,
you must cycle the power to the CVIM2 module in order to activate the
changed value.
Adding Variables
The Add function enables you to add variables that can alter or “customize”
the CVIM2 system’s performance in important and useful ways. Refer to
Appendix B for a complete list and description of the user configurable
environment variables.
To add a variable, the first step is to pick the button in the
Environment panel. When you do, the keyboard appears, as illustrated by
Figure 10.6 (Part 1).

The second step is to enter the environment variable name, the equal sign
(=), and the parameter(s) on the keyboard, then pick the
key. When
you do, the keyboard disappears and the new variable appears in the
Environment panel, as illustrated by Figure 10.7 (Part 2).
Figure 10.7 uses the “ ramdevsize ” variable as an example of a user
configurable environment variable. This variable can be used to change the
size of the
RM: device for temporary storage of files. (Since the RM: device
is volatile, files stored there will be lost whenever the CVIM2 module is
powered down.)
