The field and history output initially available in the output database are limited to those variables you have saved during the analysis. You can augment these analysis results by operating on field output to create new results. The following two methods can be used to create new field output:

• Select ToolsCreate Field OutputFrom Fields from the main menu bar or use the tool in the toolbox to create new field output variables by operating on individual existing field output variables.

• Select ToolsCreate Field OutputFrom Frames from the main menu bar or use the tool in the toolbox to create new field output by combining results from several output database frames.

This section covers the following topics:

• “Building valid field output expressions,” Section 42.7.1

• “Overview of operations on field output,” Section 42.7.2

• “Combining results from several frames,” Section 42.7.3

• “Creating field output by operating on fields,” Section 42.7.4
