To run this script
Select Scripts > Equations > Replace_Variables from the Menus.
Or, in versions that support the script, you can run the utility directly from this page using this button.
This script will do a search and replace in equations that exist in Output Equations, Schematics , System Diagrams, and Global Definitions. Once the script is run, it will give the user warning that the replacements are irreversible.
In the next step, the user will input what they want to search for and what they want to replace it with. The search and replace can be done in either the active window or all four types of windows that was mentioned earlier.
Below is a picture of before and after the script is run:
