Below are all of the DOS screens from Teledyne Microelectronics' "RF TOOLBOX" - a still-very-useful program from 1987.
This giveaway program is very well written. It looks like it may have been written in BASIC or FORTRAN and was compressed somehow by a company known as "The Software Bottling Company Of New York." This company may have developed "Screen Management Subroutines Compatible" using FORTRAN.

??? HELP for REDUCTION of VSWR by ATTENUATION ???
+------------------------------------------------------------------------------+
¦ ¦
¦ The calculation is done using the relationships: ¦
¦ ¦
¦ G = 20 * log ( (VSWR - 1) / (VSWR + 1) ) ¦
¦ ¦
¦ G (at input) = G (at load) - 2 * A(o) ¦
¦ ¦
¦ Where: G = Voltage Reflection Coefficient in dB (negative) ¦
¦ ¦
¦ A(o) = Attenuation in dB (taken as positive) ¦
¦ ¦
¦ VSWR may be expressed in many equivalent forms. If your known data is not ¦
¦ in terms of VSWR, you may use selection #6 (from the main menu) to convert. ¦
¦ If your load is known in terms of impedance, then simply take: ¦
¦ ¦
¦ VSWR = Z(l) / Z(o), for Z(l) > Z(o), or ¦
¦ VSWR = Z(o) / Z(l), for Z(o) > Z(l). ¦
¦ ¦
¦ That is, if your desired system impedance is 50 ohms, and your load is 100 ¦
¦ ohms, then the load VSWR is 2. VSWR is also 2 if the load is 25 ohms. ¦

¦ ¦
¦ The calculation is based on the work of W. J. Lucas, as reported in ¦
¦ Proceedings of the IEEE, 113, 1321-1330 (1966). ¦

TELEDYNE MICROELECTRONICS
Leader in the Science of Microelectronics Packaging and Production
Want to determine how our products, services and capabilities can
support your design and production requirements? It's easy. There's no
need for complex inquiry forms. Simply provide us with what you have
already prepared: circuit schematics, weight and volume requirements
and, if you have them, a component list, screening and test
specifications. We'll evaluate your requirements and provide pricing
and delivery information. Your inquiry will be handled in strict
confidence. Our sensitivity to security, nondisclosure policies and our
ability to protect proprietary data is another feature of our services.
Whether your application is a new system, or you wish to improve an
existing product, contact us as early as possible in your development
schedule... the sooner, the better.
