In addition to editing variables that already exist in the survey data file, you can create your own variables. This gives you the flexibility to make changes while still retaining the original variable (if you want to make changes to a variable that apply only to a single table, see also the Edit Table Variable option described in Editing variables). You can create new variables in a number of ways:
• Save an existing variable with a new name
• Copy an existing variable
• Create a new variable based on the current definition for the variable or combination of variables in either the side or the top of the table
• Merge two or more existing variables
• Create a new variable using your own definition.
