Hi,

I'm trying to get the no of days between dates for several dates. I
want to create variables days12 and days23 (see example below). I
tried to run the foll program

forvalues i = 1/2 {;
gen days`i'`i+1' = date`i+1'-date`i';
};

but I get days11 and days22 as the new variables and the values are 0.

Thanks,

Hugh
