- GENERAL DESCRIPTION
- -------------------
- RE-VIEW provides enhanced text display capabilities for the IBM PC
- or PC-XT equipped with the standard Color/Graphics Adapter. It is also
- compatible with the COMPAQ portable computer. RE-VIEW can be used with
- MS-DOS 1.0, 1.1, or 2.0. Its main features include:
- a) A 75 line screen buffer which saves text as it scrolls off the
- top of the active display page.
- b) The ability to review the 75 line screen buffer and the active
- display page together as one virtual screen of 100 text lines.
- c) The ability to scroll rapidly up and down the 100 line virtual
- screen, a line at a time or a page (25 lines) at a time.
- d) The ability to quickly pause normal screen display by tapping
- the [Scroll Lock] key. During the pause, you can review any text in
- the 100 line virtual screen.
- e) The ability to temporarily stop saving new scrolled text, so
- that text already in the buffer is preserved for future reference.
- f) An improved scrolling routine with substantually reduced flicker.
-
-
- PAGING KEYS
- -----------
- RE-VIEW uses the extreme right-hand [-] and [+] keys for page up and
- page down functions, respectively (the normal [-] and [+] keys are not
- affected). These keys are used by RE-VIEW to avoid incompatibility with
- other programs which use the [Pg Up] and [Pg Dn] keys for their own
- purposes.
- In the text below, "rgt[-]" and "rgt[+]" signify the extreme right-
- hand [-] and [+] keys, respectively. "<shft>rgt[-]" and "<shft>rgt[+]"
- signify the shifted right-hand [-] and [+] keys.
-
-
- LIMITATIONS
- -----------
- RE-VIEW only operates with the Color/Graphics Adapter. It is NOT
- compatible with the Monochrome Display Adapter. RE-VIEW's main features
- operate in the 80 column text mode only (although the quick pause feature
- can be used from any display mode). Also, the DOS 2.0 ANSI.SYS device
- driver is not compatible with RE-VIEW; however, a patching program is
- provided with RE-VIEW which will create a compatible version of ANSI.SYS.
-
-
- INSTALLING RE-VIEW
- ------------------
- RE-VIEW can be installed from DOS by typing the command: RE-VIEW
- and pressing return. Normally, you would include this command in your
- AUTOEXEC.BAT file. Once RE-VIEW has been installed, it will remain in
- your system--ready to provide the capabilities listed below--until you
- turn your system off or reboot with <Ctrl><Alt>[Del].
-
-
- USING RE-VIEW
- -------------
- RE-VIEWs features can be used any time your computer is waiting for
- keyboard input. The function of the keys used by RE-VIEW are as follows:
-
- rgt[-] or rgt[+] ... These keys allow you to quickly scroll up or down
- through the 100 line virtual screen, a line at a time.
-
- <shft>rgt[-] or <shft>rgt[+] ... These keys allow you to move up or down
- through the 100 line virtual screen, a page at a time
- (there are a total of 4 pages).
-
- <Alt>[Scroll Lock] ... This key combination allows you to toggle saving of
- scrolled text into the 75 line buffer. In order to
- help you keep track of the current state--an audible
- signal will be sounded as follows:
- 2 BEEPS - scrolled text will be saved,
- 1 BEEP - scrolled text will not be saved.
- This feature can be used to save text created by
- one program for later review by another. For example,
- you could use TYPE to display up to 75 lines of your
- program source code. Next, you would scroll the lines
- off the screen to save them in the 75 line buffer.*
- Next, you would press <Alt>[Scroll Lock] to prevent
- future scrolled lines from disturbing the contents of
- the buffer. Now, you could enter DEBUG to analyze
- your program, while--at any time--being able to review
- your commented source code using RE-VIEW's paging keys
- (rgt[-], etc.).
- * The UP.COM program, included with RE-VIEW, makes
- scrolling the text into the buffer easier--see the
- description near the end of this documentation.
-
- RE-VIEW's features can also be used while your computer is displaying
- text on the screen. First--you must pause the screen display by pressing
- the [Scroll Lock] key. During the pause you may use the keys listed below:
-
- rgt[-] or rgt[+] ... Scroll up or down through the 100 line virtual
- screen, a line at a time.
-
- <shft>rgt[-] or <shft>rgt[+] ... Move through the (4 page) virtual screen,
- a page at a time.
-
- <Alt>[Scroll Lock] ... Toggle between saving and not saving scrolled text.
-
- <Ctrl>[Scroll Lock] = "Break" ... Perform a Break immediately. Unlike the
- <Ctrl>[Num Lock] pause, the [Scroll Lock] pause does
- not throw away the key used to restart. Therefore you
- do not need to hit the "Break" key twice.
-
- Any Other Key (including [Scroll Lock]) ... Restart normal screen display.
-
-
- COMPATIBLE PROGRAMS
- -------------------
- RE-VIEW is compatible with most text producing programs which print
- to the screen using the standard DOS or ROM routines. Known compatible
- programs include:
- DIR, TYPE, <MORE, TREE, COMP, DEBUG, EDLIN, and BASIC.
-
-
- DEACTIVATING RE-VIEW
- --------------------
- Some programs will not be compatible with RE-VIEW. These include:
- a) programs which access screen memory directly;
- b) programs which use screen pages other than page 0;
- c) and, programs which use the same keys as RE-VIEW.
- When you use one of these programs or need to use the right-hand [-] and
- [+] keys for data entry, you can--temporarily--deactivate RE-VIEW by
- pressing <Ctrl><Alt>[Scroll Lock]. When deactivated, RE-VIEW will have
- no effect on system processing except for a small routine which will wait
- for the next press of <Ctrl><Alt>[Scroll Lock], which you can use to
- reactivate RE-VIEW. NOTE: you should use this feature from DOS, not from
- an application program (for example, you can deactivate RE-VIEW from BASIC,
- but must return to DOS to reactivate it).
-
-
- USING RE-VIEW WITH BASIC
- ------------------------
- RE-VIEW's features can be very helpful in BASIC, especially when list-
- ing long programs. It is also compatible with SofTool Systems' BASIC
- Development System (BDS). However, you should be aware that many BASIC
- programs will destroy the contents of RE-VIEW's screen buffer when they
- are run. Most WIDTH and SCREEN commands will clear the buffer, some other
- commands may also. However, this does not affect RE-VIEW's assistance in
- reviewing listing of large BASIC programs or the output of utilities such
- as SofTool's BDS.
-
-
- AUXILIARY PROGRAMS
- -------------------
- Three auxiliary programs are included with RE-VIEW:
- CLA.COM ....... This program provides the DOS command CLA, which
- operates like DOS 2.0's CLS command, except that
- all 100 lines of the virtual screen are cleared.
- UP.EXE ........ This program provides the DOS command UP, which
- scrolls the text above the cursor just off the
- top of the screen into the 75 line save buffer.
- (Use it with <Alt>[Scroll Lock] to save text pro-
- duced by one program for later review by another.)
- ANSIPCH.EXE ... This program patches DOS 2.0's ANSI.SYS program
- to provide compatibility with RE-VIEW (see below).
-
-
- USING RE-VIEW WITH ANSI.SYS
- ---------------------------
- If you are using the DOS 2.0 ANSI.SYS device driver, you will need to
- patch it for compatibility with RE-VIEW. The original ANSI.SYS does not
- use the standard ROM routines for scrolling. Therefore, RE-VIEW will be
- ineffective on systems using the original ANSI.SYS driver. The program,
- ANSIPCH.EXE, creates a patched version of ANSI.SYS which is compatible
- with RE-VIEW and provides all the features of the original ANSI.SYS.
- You can patch ANSI.SYS as follows:
- 1 ... Make sure the disk you are using has a copy of the
- files "ANSI.SYS" and "ANSIPCH.EXE".
- 2 ... Type ANSIPCH and press return. In a few seconds, you
- should see the message -
- "*** Patch complete. Patched version = ANSIR.SYS ***".
- 3 ... Edit your CONFIG.SYS file, changing the line -
- "DEVICE = ANSI.SYS" to
- "DEVICE = ANSIR.SYS".
- 4 ... Re-boot your system to install the patched version of
- ANSI.SYS. Now install RE-VIEW by typing RE-VIEW and
- pressing return; everything should work properly now.
- Note: ANSIPCH.EXE presumes the original version of ANSI.SYS
- (dated 03/08/83) is on the default disk drive. If it
- is not found, ANSIPCH will abort after displaying the
- message -
- "* Cannot open ANSI.SYS *".
- If ANSI.SYS is found, but does not compare with the
- original version, ANSIPCH will abort after displaying
- the message -
- "* Unfamiliar version of ANSI.SYS, patching aborted. *"
