- line option (described below). The INSTALL program inserts the correct
- path information in THELP.
-
- Memory usage
- THELP requires about 21K bytes.
-
- Default hot key
- The default hot key is Numeric-Keypad-5 (scan code 4ch,
- shift state 00h).
-
- If you are using SideKick Plus or SideKick 1.x, make sure you
- load THELP before you load SideKick.
-
-
- 2. COMMAND LINE OPTIONS SUMMARY

- 4. DETAILED EXPLANATION OF COMMAND LINE OPTIONS
- ------------------------------------------------
-
- /C#xx Select color: #=color number, xx=hex color value
-
- There are twelve possible colors, described as follows:
-
- 0 = Color border attribute
- 1 = Monochrome border attribute
- 2 = Color text attribute
- 3 = Monochrome text attribute
- 4 = Color keyword attribute
- 5 = Monochrome keyword attribute
- 6 = Color selected keyword attribute
- 7 = Monochrome selected keyword attribute
- 8 = Color example text attribute
- 9 = Monochrome example text attribute
- A = Color marked block attribute
- B = Monochrome marked block attribute
-
- The color numbers for a standard IBM-compatible Color Display are
- as follows:
-
- First Digit (Background) Second Digit (Foreground)
-
- 0 -- Black 0 -- Black
- 1 -- Blue 1 -- Blue
- 2 -- Green 2 -- Green
- 3 -- Cyan 3 -- Cyan
- 4 -- Red 4 -- Red
- 5 -- Magenta 5 -- Magenta
- 6 -- Brown 6 -- Brown
- 7 -- Grey 7 -- Grey
- 8 -- Intense Black
- ORing the color value with 9 -- Intense Blue
- Hex 80 produces a blinking A -- Intense Green
- color unless blinking has been B -- Intense Cyan
- disabled. C -- Intense Red
- D -- Intense Magenta
- E -- Intense Brown (Yellow)
- F -- Intense Grey (White)
-
- On monochrome monitors, the attribute values can differ widely,
- so some experimentation would be needed.
-
-
- /Fname Full path and name of help file
-
- The name that follows the /F option should be the full
- drive/directory path name of the help file to use; e.g.,
-
- THELP /FC:\TP\TURBO.HLP
- THELP /FC:\TASM\TASM.TAH
-
- By default, THELP looks for the help file on the logged drive and
- directory.
-
-
- /H,/?,? Display help screen
-
- This option displays a summary of THELP's command line options
-
-
- /Kxxyy Change hot key: xx=shift state, yy=scan code
-
- Virtually any shift state/scan code combination may be selected. A
- quick summary of some common shift-states and scan codes follows:
-
- Shift States (may be OR'ed together)
-
- right shift 01h
- left shift 02h
- control 04h
- alt 08h
-
- Scan Codes
-
- A --- 1eh N --- 31h 0 --- 0bh F1 --- 3bh
- B --- 30h O --- 18h 1 --- 02h F2 --- 3ch
- C --- 2eh P --- 19h 2 --- 03h F3 --- 3dh
- D --- 20h Q --- 10h 3 --- 04h F4 --- 3eh
- E --- 12h R --- 13h 4 --- 05h F5 --- 3fh
- F --- 21h S --- 1fh 5 --- 06h F6 --- 40h
- G --- 22h T --- 14h 6 --- 07h F7 --- 41h
- H --- 23h U --- 16h 7 --- 08h F8 --- 42h
- I --- 17h V --- 2fh 8 --- 09h F9 --- 43h
- J --- 24h W --- 11h 9 --- 0ah F10 --- 44h
- K --- 25h X --- 2dh
- L --- 26h Y --- 15h
- M --- 32h Z --- 2ch
-
-
- Enhanced Keyboards only (may not work with all computers, keyboards)
-
- F11 --- 57h
- F12 --- 58h
-
- /S Controls snow-checking logic for video.
-
- Some older CGA have a tendency to produce a "snow" effect when
- software tries to write directly into their memory space. If you see
- this snow you should start up THELP with /S+ to enable the snow
- checking code. You may want to use the /W switch (see below) to make
- it permanent. Snow checking takes time and it is better to live
- without it. To disable snow checking use /S-; this is the default.
-
- /U Remove THELP from memory
-
- This option removes THELP from memory. If other TSRs have been
- loaded after THELP, make sure to remove them before removing
- THELP.
-
-
- /W Write Options to THELP.COM and exit
-
- The /W parameter creates a new version of THELP that uses the
- options you desire as a default. All options may be specified
- and made "permanent."
