I am a newcomer to WinEdt 7.1 Where can I find a simple explanation for terms such as PDFTeX, PDFLaTeX, and PDFTexify?
The following, rather than an answer, wants to be a clarification...
While Doncherry is right about PDFTeX and PDFLaTeX, the meaning of PDFTeXify in WinEdt is not what one might think at a first glance.
In fact (taking the term from MiKTeX
texify executable), in WinEdt has been implemented a quite sophisticated algorithm which, with one mouse-click, performs all needed compilations to get a fully compiled document.
In other words, when in WinEdt you press the button
TeXify when you want a dvi workflow) you launch an algorithm that takes care of compiling the document itself, as well as bibliographies, indexes, glossaries, etc., to get a fully compiled document.
These commands don't necessarily make use of MiKTeX
texify program. In fact, they work both with MiKTeX and TeX Live and also succeed where MiKTeX
texify fails (eg. when launching
Moreover, these commands are customizable so you can decide, for example, to use
makeglossaries for compiling glossaries.
Some additional packages available at the site winedt.org also permit to add additional functionalities to the above commands like compiling nomenclatures, inline asymptote figures, etc.
