== XML Decode Macros ==

There are several XML variables that are returned as "flags" in an 8bit format. In order to use them you must "decode" them. This is an easy method to use as all the script is encapsulated in a set of <Macro>s for quick and simple use. Just copy/paste these <Macro> definitions to your XML gauge script.

Examples of usage are at the bottom of this entry.

// DO NOT COPY THIS! It is for reference only //
128 BIT7: 0= VOR 1= Localizer
64 BIT6: 1= glideslope available
32 BIT5: 1= no localizer backcourse
16 BIT4: 1= DME transmitter at glide slope transmitter
8 BIT3: 1= no nav signal available
4 BIT2: 1= voice available
2 BIT1: 1 = TACAN available
1 BIT0: 1= DME available

With this universal code it's very simple to control not only the length of the cycle but the frequency of the
blink itself:

Pseudocode:
<Visible>(P:Absolute time,seconds) "seed" % "blink lapse" "seed" * > !</Visible>

The seed parameter is the total length of the blinking cycle. For example, if you want something to blink once every
second, you use 1, if you want it blink every half a second, use 0.5 , every two seconds, 2 ,etc.

For each seed, you can determine how long would be the duration of both the visible and invisible part.
Then:
(P:Absolute time,seconds) 1 % 0.5 1 * > !
this will make the visible and invisible parts of half a second each.

(P:Absolute time,seconds) 1 % 0.7 1 * > !
this will make the visible part 70% of the cycle (0.7 secs) and invisible parts of 30 % (0.3 secs).

(P:Absolute time,seconds) 0.5 % 0.25 1 * > !
this will make the visible and invisible parts a quarter of second each.

(P:Absolute time,seconds) 12 % 0.5 12 * > !
this will make the visible and invisible parts of 6 seconds each.

(P:Absolute time,seconds) 12 % 0.7 12 * > !
this will make the visible part 70% of the cycle (8.4 secs) and invisible parts of 30 % (3.6 secs).

You can invert the cycle by removing the "!" char.
