Hello Statalist. Happy New Year.

This post is an extension of a previous post of mine that I've yet to fully solve: https://www.statalist.org/forums/for...-based-on-week. One addition I've made since that post is that I created a variable called -week- that essentially counts up, by 1s, for each Thursday-to-Wednesday "week". I'm hoping that may make looping potentially easier...

Essentially, what I'm hoping for is generating a new variable: once -attend- is a 1 within a Thursday-to-Wednesday week, then all days in that week following (i.e., up until the next Thursday) are also a 1.

As a concrete example, in the data I provided: for id 16482, on Thursday, January 9, 2020, that is a 1 for -attend-. Therefore, the Friday, Saturday, Sunday, Monday, Tuesday, and Wednesday following it should also be a 1--but we can see that the Friday and Saturday immediately following are both 0s. There are a few variations of this throughout the data example, and most simply put, I'm hoping to get some code that make those 0s into 1s.

I've been trying to work with some code that uses a foreach loop and local macro based on Nick Cox's suggestion (but my modification fails due to syntax error):

Code:
 
 sort id date  gen work = .   gen wanted = attend  local D = 6   foreach d in 4 5 6 0 1 2  {        replace work = cond(attend == 1 & week_day == `d', date, .)          by id : replace work = work[_n-1] if work == 0       by id: replace wanted = wanted[_n-1] if wanted == 0 & inrange(date - work, 1, `D')        local D = `D' - 1  }
Code:
