HeatIndex(); EXPORT HeatIndex1() BEGIN END; VIEW "Start HeatIndex",START() BEGIN t:=AVars("t");rh:=AVars("rh"); STARTVIEW(-1,1); WHILE GETKEY<>4 DO     REPEAT tmp:=INPUT({{t,[0],{60,20,1}},        {rh,[0],{60,20,2}},        {hi,[0],{60,20,4}},        {hi2,[0],{60,20,5}} },        "Heat Index Input and Output",        {"Temperature, Deg F  : ",          "Relative Humidity, %  : ",         "Heat Index, Deg F  :",         "Heat Index, Deg F  :" },        {" Air Temperature (80 to 104 °F)",         " Relative Humidity (40 to 100 %)",         " Heat Index from www.weatherimages.org",         " Heat Index from www.4wx.com" },        {t,rh,hi,hi2},        {t,rh,hi,hi2}); AVars("t"):=t;AVars("rh"):=rh;     IF tmp==0 THEN     STARTVIEW(-4,1);     MSGBOX("End of Program");     RETURN;     END;     UNTIL t>=80. AND t<=104. AND rh>=40. AND rh<=100.;  HeatIndex(); END; // While STARTVIEW(-4,1); MSGBOX("End of Program"); END; HeatIndex() BEGIN // This is the 16 element equation used to convert // dry bulb temperature (T) and relative humidity (RH) // into the Heat Index. This equation works at // dry bulb temperatures of 70°F and higher. // The symbol  "^"   means  "raised to the power of". //  Source: http://www.weatherimages.org/data/heatindex.html //  Where: //  hi = Heat Index //  t = Temperature (° F) //  rh = Relative Humidity (%) tmp:=16.923; tmp:=tmp+1.85212*10^(-1)*t; tmp:=tmp+5.37941*rh; tmp:=tmp-1.00254*10^(-1)*t*rh; tmp:=tmp+9.41695*10^(-3)*t^2; tmp:=tmp+7.28898*10^(-3)*rh^2; tmp:=tmp+3.45372*10^(-4)*t^2*rh; tmp:=tmp-8.14971*10^(-4)*t*rh^2; tmp:=tmp+1.02102*10^(-5)*t^2*rh^2; tmp:=tmp-3.8646*10^(-5)*t^3; tmp:=tmp+2.91583*10^(-5)*rh^3; tmp:=tmp+1.42721*10^(-6)*t^3*rh; tmp:=tmp+1.97483*10^(-7)*t*rh^3; tmp:=tmp-2.18429*10^(-8)*t^3*rh^2; tmp:=tmp+8.43296*10^(-10)*t^2*rh^3; hi:=tmp-4.81975*10^(-11)*t^3*rh^3; hi:=ROUND(hi,0); //  Source: http://www.4wx.com/wxcalc/formulas/heatIndex.php tmp:=-42.379; tmp:=tmp+2.04901523*t; tmp:=tmp+10.14333127*rh; tmp:=tmp-.22475541*t*rh; tmp:=tmp-6.83783*10^(-3)*t^2; tmp:=tmp-5.481717*10^(-2)*rh^2; tmp:=tmp+1.22874*10^(-3)*t^2*rh; tmp:=tmp+8.5282*10^(-4)*t*rh^2; hi2:=tmp-1.99*10^(-6)*t^2*rh^2; hi2:=ROUND(hi2,0); END;``` I want to take the subroutine HeatIndex(), and move it to the AFiles folder of this app. For me, the explanation in the AFiles help section of the emulator is inadequate. I need help in how to structure the code in order to run this App with the subroutine HeatIndex() in the AFiles folder. Thanks for any help you can provide. rcf RE: How do I use AFiles in an App? - eried - 07-14-2015 03:22 AM What exactly do you want to do? each app has its own "script" place, the "Afiles" is (I believe) for external resources (in this moment probably text or images), not for script objects, like 'libraries' RE: How do I use AFiles in an App? - cyrille de brébisson - 07-14-2015 04:34 AM Hello, Application files are for data, not programs. You can store 2 type of things in files using AFiles:Math "Objects" (anything that you can place in a variable) using AFiles("name"):= var (or directly object), and graphics (storing G0-G9). You can not store a program in a file, sorry. At this point in time, your program still has to be one single unit of source code. Cyrille RE: How do I use AFiles in an App? - Bob Frazee - 07-14-2015 09:39 PM Thanks very much for your answers. I now have the answer to my question. rcf
