**NAME**

formed - formula editor for first-order logic formulas

**SYNOPSIS**

formed[options]

**DESCRIPTION**

This manual page documents briefly theformedcommand.formedis a window-based program for constructing, displaying, and managing first-order logic formulas. The main motivation for constructingformedwas the desire to have formulas displayed in a readable, two-dimensional format. Users offormedcan make two kinds of transformation on formulas: (1) logic transformations, such as negation normal form translation, which preserve the meaning of a formula, and (2) edit transformations, which can be used to make arbitrary changes, such as adding a hypothesis to a subformula.formedwas written by using the X Window System, Version 11, and code from the theorem proverotter.

**OPTIONS**

A summary of options is included below.-lfilenameLoad formulas in the specified file during startup. Formulas can also be loaded after startup with the buttonLoadin the main menu.-fcolorUse the named color for the foreground on color monitors (ignored on black-and- white monitors).-bcolorUse the named color for the background on color monitors (ignored on black-and- white monitors).
