NAME
formed - formula editor for first-order logic formulas SYNOPSIS
formed [options] DESCRIPTION
This manual page documents briefly the formed command. formed is a window-based program for constructing, displaying, and managing first-order logic formulas. The main motivation for construct- ing formed was the desire to have formulas displayed in a readable, two-dimensional format. Users of formed can make two kinds of transfor- mation 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. formed was written by using the X Window System, Version 11, and code from the theorem prover otter. OPTIONS
A summary of options is included below. -l filename Load formulas in the specified file during startup. Formulas can also be loaded after startup with the button Load in the main menu. -f color Use the named color for the foreground on color monitors (ignored on black-and-white monitors). -b color Use the named color for the background on color monitors (ignored on black-and-white monitors).
