st: Picking out first date from a series conditional on values of other variables

Hello all,
I am analyzing a dataset for medication compliance.
I am interested in the first day that there was a break in medication
possession. From the date variables (disp_date1-disp_date14 OR
disp_date`k'), I need to pick out the first date of the break for each
patient where
variable A`k' > variable B`k'.
I've been trying for hours but I can't get Stata to do exactly what I
want. I tried -egen-, and some loops but to no avail.
Does someone have any inputs?
