P3Dv3 Script didn't work anymore in P3Dv4

[Airbuspilot]

Need Help about the attached Scripts.

In P3Dv3 with FSUIPC 4.9xx they worked well. Now in P3Dv4 with FSUIPC 5.103 the Following Error occured:

318797 *** LUA Error: ...\Simulatoren\Fliegen\P3Dv4\Modules\B777FuelInput.lua:6: attempt to index global 'file' (a nil value)

Please have a look at the attached FSUIPC5.log. Maybe you can provide some Help.

Thanks in Advance

A brief look at the Lua file involved shows "file" being set as follows:

file = io.open("e:\Temp\Flusis\B777InitialFuelQty.txt", "r")

So a value of "nil" just means the file.open attempt failed. You should really check for such an error in your script.

The likely reason it failed is that within strings in Lua the \ character is an escape character, allowing all sorts of controls to be added, like \n for "newline2. To get a true \ you must use \\, so:

file = io.open("e:\\Temp\\Flusis\\B777InitialFuelQty.txt", "r")

Check, of course, that the file is actually there!
