DOSWEB0 v0.32 by ODP © - help


Contents


Purpose


DOSWEB0 is a simple HTML viewer for fast HTML preview from DOS. It can't pretend to support a complete HTML 2.0-3-4.0, but quickly loads and is comfortable to use program.

Help


DOSWEB0 works in text regime and don't change it, what's why it display different size and font of symbol as different colours. For simpicity DOSWEB0 does not recognize tag <FONT>. Symbol on blue background signifies anchor, on grey - inline image.

I did a weak try to recognize tables with a little result. All types and levels of lists will be displayed as simple unnumbered list. Works tag <CENTER> (not in tag <P CENTER>). DOSWEB0 can understand anchors in file and to local files.

I implement file of extensions - it must be in same directory with DOSWEB0 and have a name DOSWEB0.EXT. In this file must be program calls for work on included data files (not inline!!!). For example:

 JPG: VJPEG !.!
 EXE: HIEW !.!
 ZIP: ARCVIEW !.!
Single understandable mask is !.! where DOSWEB0 will insert full name of data file. Files with other extensions will be recognized as HTML files.

    From version 0.29 were corrected jump to a local files, loading of files and added color setup (color data will be saved in DOSWEB0.EXE).

    From version 0.30 were corrected entering of search string, default color palettes, work with cursor, search of anchors in Russian, jump back by Backspace.

    V0.32 - fixed some small bugs, added some tiny features.

    Please, don't kick me for bad English - it is not my first (and even second) language, and I have not use someone's or speller help for writing this.
