To determine which numeric variables exist in a database, create a configuration file, named flip.cnf, containing one line of the form:

or

The flip configuration file provides additional control over the way a Quanvert database is created from a Quantum program and data file. Currently, it is only used for numeric variables.

A Quantum flip run normally creates one numeric variable for each namedinc= in the run. By placing statements in the flip configuration file, you can exercise more control over exactly which numeric variables are created.

The statement which controls numeric variables is:

Note the semicolon at the end of the specification.

Quantum recognizes four specifications:

to flip all numeric variables; this is the default if there is no configuration file.

to suppress all numeric variables.

to flip all numeric variables except those named on this statement.

to flip only the named numeric variables.

As the database is created, Quantum builds a flip output file reporting which numeric variables have and have not been flipped. For example, if the flip configuration file contains the line:

and the variables serial, numpots and total exist in the data, the flip output file contains three statements:

The names of the flip configuration and output files are flip.cnf and flip.out.
