Gauge variable help please

[FrankFasi 0]

Here's the variable I'm working on. It returns the current heading just fine, but what I'd like is for it to always return the reciprocal heading. For example, if I'm flying a heading of 90, I would like this gauge to show me "270", the reciprocal. Here's my current string from the gauge element in question:%((A:PLANE HEADING DEGREES GYRO,degrees))%!03d!Any ideas are welcome. Thanks.

Add 180, then the string becomes:%((A:PLANE HEADING DEGREES GYRO,degrees) abs 180 +)%!03d!The ABS is to make sure that an absolute value is given.

Remember to normalize it too.. HDG 350 + 180 = 530 normalize will make it 170%((A:PLANE HEADING DEGREES GYRO,degrees) abs 180 + dnor)%!03d!Roman
