What is the .FWEB File Extension?

.FWEB File Extension Description:

The FWEB file extension is used by the application Fortran WEB. This application is a web processor for the languages C, C++, Fortran, including Fortran 77 and Fortran 90, Ratfor and TeX. The FWEB file extension is created by Knuth's WEB system to support the different languages mentioned above. There are different user manuals available, which give details on the philosophy behind WEB including other details pertinent in using the Fortran WEB. These user manuals include the fweb.tex, which are also available online as a text info or system, using GNU hypertext with the entry name info FWEB.

For UNIX systems, the FWEB file extension is an initialization file placed in the home directory. Files containing the FWEB file extension can be located anywhere, depending on allowed options in the command line, where only one option should exist per line. The following options are followed, and options beginning with a hyphen are executed before the command line. When it begins with an ampersand, it is executed after the command line; if it begins with neither symbol, it is then interpreted as a file name that is just executed after the command line.

The FWEB file extension has different options that can be used. The filename option is the very first file name, which works by pointing to the source file used. If there exists a second filename, then that would signify a change in the file. The -@ option will show information about the control codes. The -Cn will define the color mode, where n corresponds to different colors as defined by the user. The -e option will activate the automatic file name completion function. The -k will identify the lower case version of the keywords (Fortran, Ratfor, I/O). The -n (for Fortran 77) will automatically provide semi colons. The -np option will produce semi colons in the resulting Fortran output. The -n/ will utilize a free form in syntax for the Fortran 90. A complete list of this features and options is provided in the manuals stated above.
