The code line 

 

<GaugeString>%((A:Plane heading degrees gyro,degrees))%!03d!</GaugeString>

 

  is used to generate a heading value that is to be displayed on an a/c PFD.

 

I wanted to reduce the value displayed by one degree and thought the following would work, but it doesn't:

 

<GaugeString>%((A:Plane heading degrees gyro,degrees) 1-)%!03d!</GaugeString> .

 

My understanding is the !03d! code section formats the result to 3 digits, and I thought my addition in red would reduce the heading value by 1 before that took place. Clearly I don't understand something basic here. Would appreciate any advice.

 

Would also appreciate recommendations for a good online XML tutorial.

 

Thx,

Al

 

Try inserting a blank between 1 and - .

Bert,

That solved the problem. I would have sworn I had tried that first, but apparently not.

Thanks!

Al

I think you could also use -- (ie. decrement) instead of 1 -
