Me to.It always depends how you want to write the coordinates. You need (degrees).(fractional degrees), West and South counted negative.What I assume is,that you meant North 33 degrees , 28 minutes , 43 fractional minutes or in FS standard notation N33*28.43' then it isN33*28.43' -> 33+28/60+0.43/60 or 33+28.43/60-> 33.47383If it is North 33 degrees , 28 minutes , 43 seconds or in FS with fractional seconds enabled N33*28'43.0''it would be N33*28'43.0'' -> 33+28/60+43.0/3600 or 33+(28+43.0/60)/60-> 33.47861BTW (28+43.0/60)/60 is again the recursive Horner scheme decribed in the XML FAQ for BCD conversions.It can't be the West longitude in degree* minute' second'' notation because minutes and seconds are always smaller then 60.Arne Bartels

Arne,So i can always use:N x.y.z = x+y/60+0.z/60S x.y.z = -1*(x+y/60+0.z/60)W x.y.z = -1*(x+y/60+0.z/60)E x.y.z = x+y/60+0.z/60?Good Sunday,Jan"Procul Negotiis"

Yes.I feel a bit uneasy about using the decimal seperator "." both for separating degrees from minutes and minutes from fractional minutes, but I might be a bit pedantic.Arne Bartels

Arne,Now i can put the formula's in Excel,so calculating waypoints will be a piece of cake.(Btw. EHAM-KATL was uneventful)Jan"Procul Negotiis"

Arne,Is there any way to put text to a L: variable?

As far as I know, no. It might be possible to use the ASCII code of the string to encode it as numeric value in a L: variable and later decode it again, but I assume it is then limited to only few chars. At least four chars need the same place as one integer.Arne Bartels

Here we are again,Is it possible to use a variable which compares(A:Nav1 (Nav2 or Adf) ident, string) with a given letter combination?Par example:...ATL = (A:Nav1 ident, string).....if{ (A:NAV1 radial, degrees) 180 + (>K:HEADING_BUG_SET) }Jan"Procul Negotiis"

Try: (A:NAV1 IDENT,string) 'ATL ' scmp 0 == if{ (A:NAV1 radial, degrees) 180 + (>K:HEADING_BUG_SET) }scmp and scmi result 0 if the strings are equal ,-1 if the first string is smaller, 1 if the first string is greater. Also make sure you use a four-letter string (trailing spaces) to compare.Arne Bartels

Arne,What do i owe you..It works!Again something to put in the FMC.Where is the "scmp" from?Cannot remember to have read something about it.Until..Jan"Procul Negotiis"

Panel SDK from Microsoft. I wasn't able to get any sense out of the Extact/Find operators the other string ops work fine.Arne Bartels
