• OK accepts the current settings and data, and subsequently closes the form or window.
• Cancel closes the dialog box without saving or executing a command..
• Save Only saves the created code to the Program Editor, but does not run the code.
• Help opens the Help topic associated with the module being used (Currently Disabled).

QUIT

The Quit command closes the current data files and terminates the current program, closing Analysis.

Figure 9.60: Quit Command Box

• OK accepts the current settings and data, and subsequently closes the form or window.
• Cancel closes the dialog box without saving or executing a command.
• Save Only saves the created code to the Program Editor, but does not run the code.
• Help opens the Help topic associated with the module being used (Currently Disabled).

Use IF Statements with Permanent or Global Variables

• If an IF statement condition depends on global or permanent variables, the value is computed immediately and only the true or false branch, as appropriate, is followed.
• If an IF statement condition depends on a field variable, neither branch is followed. However, computations within the branches are saved for execution, as appropriate, on each record. In the second case, non-computational commands (e.g., READ, SELECT, SORT, HEADER, and ROUTEOUT) are never executed.

SET

Description

This command provides various options that affect the performance and output of data in Classic Analysis. These settings are utilized whenever the Classic Analysis program is used.
