Hi Pete, I'm using FSUIPC since years but I never tried to create program working with it. My question is the following: The values FSUIPC reads are populated as GLOBAL variable? I have a scenery asm file and I would like to set a condition for a parameter which is populated by FSUIPC. To be more precise: I want a light to show up when the visibility dropes under a specific distance. I have checked the FSUIPC documentation I found the 04C0 variable as visibility in statue miles: IFIN fog, 04C0, 0000h, 00C8h BGL_LIGHT LIGHT_NAV, -0.083, 1.103, 0.083, 20, 0.60, 0.40, 0FFFFFFFFh, 0.000000, 0.000000, 1.000000 ; source poly num = 1 fog label BGLCODE BGL_RETURN Unfortunately I can not compile this asm. I have an error saying: "nondigit in number" Do you have any suggestion how could we solve this challange? Thank you so much for your support in advance!
