- Filename: STFTUT.OLD Copyright (c) 1993 by RPMcCormick
- STF compares 2 ASCII text files side-by-side.
- In the default text mode, only the first 39
- characters are visible. There are 3 things you can
- do to see what is currently hidden.
- 1. Hold down the <Ctrl> key and hit the
- right arrow several times. Notice the Sliding
- Centerline.
- 2. Use the Right arrow key by itself, that is,
- without the <Ctrl> key. This moves your
- viewing position 10 columns to the right.
- Note that for one Right Arrow, a "+10" appears
- on the top info bar. Scroll back with the Left
- Arrow, and the "+10" disappears.
- 3. If you have VGA graphics, hit the F6 function key.
- That gives you a view of the file using a custom font
- which allows you to see 62 columns initially.
- Use the F5 function key to return back to text mode.
- This resets the centerline to the middle of the screen.
-
- -- Please hit the "Page Down" key to continue. --

-
- If two lines are identical, they are both
- bright white. If a line is different, the
- version on the right is dimmed. The top lines in
- this demo are different due to the filenames.
- This comparison is case sensitive. An upper case letter
- is considered different from lower case. Note that on
- this line, arrow is not capitalized in the .OLD file.
- Sometimes lines will show up as different when they
- appear identical to you. This may be due to
- an unseen extra space as in this line,
- or a "tab" character as in this one, or an
- extra Carriage Return like this line has.
-
- If you would prefer that these are not marked
- as different, hit the <Alt> B key to "toggle"
- blanks. Try it now. Notice the lines on the right
- are no longer dimmed. You can see the current
- state of this 2 position toggle in the first
- help file screen. Access the help screen by using
- the F1 function key. To get right back here,
- hit Escape.
-
- When one or more lines are inserted in one file and
- not the other, they will get out of synchronization.
- All lines will appear as unequal, or different. To
- re-synch these files, first observe the bright white
- squares before each filename on the top information
- bar. By default both files are active, so both bright
- squares are "on". Hit F4 to make file 2, the one on
- the right, active, while deactivating file 1. Note
- that the square for file1 has extinguished. Now hit
- the up arrow key twice to bring the files back into
- alignment. Hit F2 to make both files active as before.
-
- To search for text, use <Alt> F. The F is for Find.
- We will search for the string "Home" without the
- quotes. You can enter the letters in upper or lower
- case, as case is ignored in the search. Imbedded
- spaces do count, however. Go to the start of the file
- by hitting the Home key, then hit <Alt> F. You will
- be prompted, on the upper info bar, to enter the
- search string after the word Find: type in "home" and
- hit the Enter or Return key. This should bring you
- back here. Hit <Alt> A to search for "Home" again.
- -- Please hit the "Page Down" key to continue. --
-
- If you want to cancel your "find" while entering the
- search string, you can hit the Escape key. Note that
- the search works only on file 1.
-
- If you have been following this tutorial, the files
- will be "out of synch" at this time. To get them back
- in line, activate File 2 and hit 2 up arrows. Then
- activate both files with the F2 key.
-
- For items not covered in this tutorial, read the help
- screens, which can be reached either by the F1 key while
- active, or by typing "STF h" at the DOS command line.
- Also see the file STF.DOC. To view the .DOC file now,
- hit Escape to see the current directory, then select
- STF.DOC from the list. When asked for the second file,
- choose "No 2nd file" from the second directory screen
- to view the .DOC file full width. When finished, you
- can "back out" by hitting Escape until you are back
- in DOS, or use "<Alt> X" for a quick exit.
