Contents of the READ.ME file
This file contains three examples of menu systems built using the 4DOS
batch file language and built-in functions. The examples are:
** GAMES.BTM uses 4DOS line drawing feature to build an attractive
function key-based menu interface for program selection. My version
is used for a games menu, but the programs could be anything.
** MAN.BTM uses the 4DOS %@select function to allow selection of a file
from among those in a .ZIP file. The selected file is then extracted
into a file viewer. I use this for keeping infrequently referenced
utility .DOC files in an archive to minimize the space they take up.
** RFC.BTM also uses the 4DOS %@select function. In this case, I'm using
it for a .ZIP file of documents whose file names are not indicative of
their contents (numbered files, basically), so the menu selection is
driven off an external text file that gets updated manually when the
a new document is added to the .ZIP file. The file RFC_LIST is the
external used to drive the menu.
MAN and RFC also demonstrate use of the %@substr function to extract a piece
of a string to get the file name.
These files are fairly well commented, and should be understandable.
Hopefully the ideas presented here are useful to someone. Comments are
welcome. Feel free to modify and/or distribute these files freely.
