Hi,

Yet another question regarding an areadetector driver I am writing (which is now mostly finished). 

For some reason my parameter library is not getting set to the correct indices. In my writeInt32 function I put some printf statements and found out that my first parameter VarianMode is set to 3, but should be set to 78. (or vice versa?)

synStatus varian::writeInt32(asynUser *pasynUser, epicsInt32 value)
{
    int function = pasynUser->reason;
    //int status = asynSuccess;
    printf("VarianMode: %i", VarianMode);

    printf("writeint32 %i %i", function, value);
   if (function == 78){
        printf("function varian mode called");
        vip_select_mode(value); //varian function 
}

(Explicitly just saying function ==78 was my quick fix to get things working as expected). 
When I caput VarianMode 1
the first printf gives: VarianMode: 3
The second printf gives: writeint32 78 1

I've compared my code to many areadetector examples and can't figure out what I am doing wrong? Everything I'm doing seems exactly the same - 
the declarations, the NUM PARAMS define (which is later used in the constructor)
#define NUM_VARIAN_PARAMS ((int)(&LAST_VARIAN_PARAM - &FIRST_VARIAN_PARAM + 1))

Any ideas?

Thanks,
