Hi Stata Users,

I am using Stata 17 with the commands below to post results to file but for some reason the file ends up empty

Code:
    local DHSdir "D:/Data/1-CleanInput"
     
    local files : dir "`DHSdir'" files "*HR*.dta"
    
    tempname memhold
    tempfile results
    
    postfile `memhold' str10(survey) str40 (vlab) double(q1 q2 q3 q4 q5) int(q1_o q2_o q3_o q4_o q5_o) using `results'
    
    foreach f of local files {
        local f = substr("`f'", 1, strpos("`f'", ".")-1)
        di "`f'"
        local f_n = subinstr("`f'", "hr", "pr", .)
        di "`f_n'"
        
        if !inlist("`f'", "drhr21fl", "hrhh21fl", "pkhr52fl") {
            use "`DHSdir'/`f'", clear
            capture confirm variable hv005
            if !_rc {
                gen wt=hv005*hv012
            }
            
            capture confirm variable hv271
            if !_rc {
                xtile windex10=hv271 [pweight=wt], n(10)
            }
        
            *drop hv106*
            
            capture confirm file "`DHSdir'/`f_n'.dta"
            if !_rc {
                
                qui merge 1:m hhid using "`DHSdir'/`f_n'", keepusing(hv106) assert(3) nogen
                
                local vlab: variable label hv106
                di "`vlab'"
                
                *** Number of observations
                qui tab hv106 hv270, matcell(y)
                mata: st_matrix("yy", colsum(st_matrix("y")))
                matrix list yy
                
                *** Percent
                qui tab hv106 hv270 [aw=hv005], matcell(x)
                mata: st_matrix("xx", (st_matrix("x") * 100) :/ colsum(st_matrix("x")))
                * matrix list xx
                
                post `memhold' ("`f'") ("`vlab'") (xx[1,1]) (xx[1,2]) (xx[1,3]) (xx[1,4]) (xx[1,5]) (yy[1,1]) (yy[1,2]) (yy[1,3]) (yy[1,4]) (yy[1,5])
                post `memhold' ("`f'") ("`vlab'") (xx[2,1]) (xx[2,2]) (xx[2,3]) (xx[2,4]) (xx[2,5]) (yy[1,1]) (yy[1,2]) (yy[1,3]) (yy[1,4]) (yy[1,5])
            } 
        }
    }
    
    
*** Clean dataset
    use `results', clear
    brr
Attached are the files for easy reproducibility of the issue.

Thanks in advance!
