Hans,
here is a function I wrote to translate AMI dates into a day number:
function ws_toDayNum( adate)
{
strDate=NumToStr(adate,7,False);
yr= StrToNum(StrMid(strdate,1,2));
mo=StrToNum(StrMid(strdate,3,2));
dy=StrToNum(StrMid(strdate,5,2));
adj=(mo>1) +( mo>3) + (mo>5) + (mo>7) + (mo>8) + (mo>10) + (mo>12)-
((mo>2)*2);
return ( yr*365) +( (mo-1)*30) +dy +adj;
}
>>Note: This does not account for leap years...
