I've not used all the string variables - I'm tending to learn them as I go along. !6.2f! is used to display a readout like 123.45 with .2f denoting two decimal places. !02d! produces just a two integer digit like 23, ideal for DME time to station. !03d! is better for G/S and Hdg !s! must be specific to a text string. bones -----Original Message----- From: jhb_airlines-bounce@xxxxxxxxxxxxx [mailto:jhb_airlines-bounce@xxxxxxxxxxxxx] On Behalf Of FrankTurley@xxxxxxx Sent: 01 September 2006 08:50 To: jhb_airlines@xxxxxxxxxxxxx Subject: [jhb_airlines] Re: XML Gauges In a message dated 31/08/2006 22:12:48 GMT Daylight Time, bones@xxxxxxx writes: What's the difference between NAV1 Ident morse output and NAV1 station display code? To me Ident means the former. bones Sorry Bones, I'm not sure. The code I used displays e.g. NAV1 CPT when tuned to 114.35 the Compton VOR. There is a variable called NAV1 CODE (or CODES), I didn't experiment with that as I found NAV1 Ident was used in the 747 CAB file. I'm guessing the !s! is some sort of format instruction, probably required because the Ident variable type is not a simple string. Frank T.
