Reorder variables and parameters in a Case Study

The Case Study manipulates the variables in nested loops. The order of the variables and parameters determines how the loops execute, and is therefore very important.

For example, consider the situation where we have two manipulated variables, A and B. If A appears before B in the list of variables, the Case Study runs all steps for B while keeping A constant. It then increments A and runs all steps for B again. It repeats this cycle until it reaches the maximum value of A, as shown in the following figure.

Currently, you must delete and re-add parameters and variables to change their order in the list of variables and parameters.

Move a variable or parameter in a Case Study to the bottom of the list

1. On the Case Study Editor, in the Variables and Parameters area, delete the variable or parameter from the Case Study by doing one of the following:

   • Select the variable or parameter, and then select Delete manipulated variable(s) or parameter(s) or observed variable(s) .

   • Select the variable or parameter, and then select the Delete key.

2. Re-add the variable or parameter to the Case Study. See Add a variable or parameter to a Case Study for more information.

   The variable or parameter now appears at the bottom of the list.

3. If the variable or parameter is a manipulated variable or parameter, re-specify it as a manipulated variable or parameter. See Specify the manipulated variables and parameters for a Case Study for more information.

Move a variable or parameter in a Case Study to the top of the list

4. On the Case Study Editor, in the Variables and Parameters area, delete all other variables and parameters from the Case Study by doing one of the following:

   • Select all other variables and parameters, and then select Delete manipulated variable(s) or parameter(s) or observed variable(s) .

   • Select all other variables or parameters, and then select the Delete key.

   The variable or parameter now appears at the top of the list as the only variable or parameter in the Case Study.

5. Re-add the deleted variables and parameters from the preceding step to the Case Study. See Add a variable or parameter to a Case Study for more information.

6. If any of the deleted variables or parameters were manipulated variables or parameters, re-specify them as manipulated variables and parameters. See Specify the manipulated variables and parameters for a Case Study for more information.
