/* Mach1.6a - Mouse Accelerator with Hotkey **** 02-10-88 ****
MachClk1.2a - and clock with beeper and meter.
Copyright 1988 by Brian Moats @Polyglot Software.

run mach [nambscqwekp] hotkeystring hotkeystring...hotkeystring
Arguments: All optional. Any order.
-n Accelerator factor where n >= 0 && n <=9.
-a Switchs hotkey qualifier from Alternate to Amiga.
-m Removes the trapping of left-amiga-m. (allows normal use)
-bnnn Time delay before blanking screen. 0-999 minutes. 0 = no blank.
-s Removes sunmouse.
-c Removes click to front.
-q Adds qualifier accumulating feature.
-w Disables auto clock to front. Adds depth gadget.
-estr Use str as execute command string. Default = NewCLI.
-knnn nnn > 0 put clock left edge at nnn. If nnn = 0, don't use clock.
-tnn Set beep time interval to every nn minutes.
-pnnnn Set online rate. nnnn = pennies per hour. Default = 475.
Usage eg. Run Mach -3 -m -a -b10 df0: df1: copy dir\n rename "blank space"
How to build this:
Simple (with Manx). I used version 3.4.
cc machclk
ln machclk.o -lc
Changes from version 1.6
1. New toggle -w will disabled the auto clock to front and add an
(mostly) invisible depth gadget to the clock window.
2. Fixed orphaned clock window resulting from rapid F8 toggling.
Changes from version 1.5:
1. Uses UpfrontLayer() instead of WindowToFront() for the clock to prevent
lockups. Before, I was keeping track of the left mouse button and
not doing a WindowToFront() if the button was down because you may
be holding an icon. But...WindowToFront() doesn't actually happen
until the next event and if it happened that that event was a left
button down on an icon, bingo! it locks up. Sigh...live and learn.
2. Allocate 1 byte for null in hotkey and execute definitions.
3. Changed double control feature. Now you use -q. When you do, any
shift, alternate, amiga or control key is added to the next non-
qualifier key. This is intended primarily for disabled people who
find it difficult, if not impossible, to hold down two or more keys
at once. This accumulates qualifiers so you can hit for example,
control, shift, alternate and then F1. This is the same as typing
them at the same time. Hitting Caps Lock will reset the accumulator.
4. Return value (rv) changed to long. If there is an error and if
short, it will crash when run from Runback but will set the returncode
when run from Run. If long, it won't crash but won't set the returncode
when run from Run. ??? Any ideas?
Problem: The uninstall "Control-Qualifier-F1" and the Instant Screen
Blanker don't work right if defined in a hotkey. e.g. \c\A\2
doesn't blank the screen and \c\A\1 doesn't uninstall.
