- DESCRIPTION
- -----------
-
- FView is a simple, text file viewer program. Since I didn't have one, nor was
- able to quite find the one I liked, I built my own. (Like they say, if you
- want something done right you gotta do it yourself.)
-
-
- USAGE
- -----
-
- Starting the program is simple. From any DOS prompt, type:
-
-
- FVIEW {-ns} filename
-
-
- This will scan through the specified file, then display it on screen. Much
- like DOS's edlin, the filename MUST be specified.
-
- The "-ns" is an option. If specified, no scroll bars will be displayed and
- the mouse will not be enabled. Use this if the text file to be viewed
- contains lines of 80 characters and you wish to be able to view the entire
- line without having to scroll left and right.
-
-
- NAVIGATING THROUGH THE FILE
- ---------------------------
-
- New in version 2.2 is the addition of horizontal and vertical scroll bars,
- which show your relative position within the file. If you have a mouse, you
- can use the scroll bars to navigate through the file.
-
-
- While viewing the document, you can scroll up/down/left/right/etc... using
- the cursor keys, page up/down keys, home and end keys (HOME takes you to the
- beginning of the file, END takes you to the bottom). As you move around, the
- current line and column will be display in the status bar.
-
- Note that although the left and right cursor keys scroll a full screen rather
- than one character at a time (as the scrolling would be noticably slow), you
- can use the box in the horizontal scroll bar to move more precisely. Simply
- click on the box and drag it left or right. Release it where you want it. This
- goes for the vertical scroll bar as well, so you can select where in the file
- you want to view.

-
-
- To search through a file, hit 'F', or click on 'F' or 'FIND' in the help line.
- This will bring up a box to type the text in that you wish to search for. When
- you hit ENTER, it will begin searching through the file, starting with the
- current line as indicated in the status bar at the top. To quit from the input
- box, hit ESC. Note that you cannot abort a search in progress.
-
- While in the input box, standard editing keys are in effect, ie. left/right
- cursor keys, home/end, insert, etc. Use CTRL-HOME to erase the input and start
- over at the first position (CTRL-X also erases). When you first enter the box,
- the last text string (if any) you entered will be displayed. You can edit this
- string or start with a new one. If you begin typing characters immediately,
- before you move the cursor, the previous text string will be erased first.
-
- To continue a search, hit 'N', or click on 'N' or 'NEXT' in the help line. This
- will continue the search from where the last text was found (even if you've
- scrolled it off the screen). If you hit 'N' before you've selected text with
- 'F', then a box will be displayed for you to enter the text.
-
- Similarly, hit 'P' or click on 'P' or 'PREV' in the help line to search
- backwards from the last found text. The program will beep if you have hit 'P'
- before entering text with 'F'.
-
- In all 3 cases, if the text string is not found, it will beep and display
- "Search string not found". (It doesn't loop back around from the end of the
- file to the beginning, or vice-versa).
-
-
- To leave the program, hit the ESCape key, or click on "ESC QUIT" in the help
- line. You will NOT be asked for confirmation.
