AHK: Comparing Two Txt Files - loops

Question

So I'm doing billing for a doctors office, and we like to triple check that the flu shots we give are actually billed out. Right now, my AHK checks their entire chart for keys like the ICD-10 Code Z23, then checks for "Influenza". If it finds both of these, it adds the patients Medical Record Number to the age appropriate text file, either 65+ or Under 65. There are also paper sheets with 10 slots we record the MRNs by hand on, to double check. I want to create a script that will compare three files, a file of mixed MRNs (both 65+ and <65), and if the MRN is found in the mixed file, it should remove that line. (I've done a bunch of googling on the subject, but everyone is recommending using a library, something that would only slow down my program.) If the line isn't found, it should be left in the master file for my review. I cannot figure out how to remove lines, let alone a specific line. So far, to check the files against each other, I have this. In lieu of removing lines, I'm appending the unbilled numbers to a fourth text file, but ultimately, removing would be better.
FILENUM = 1
FILENU = 1
^L::
Loop
{
FileReadLine, MRN, E:\AHK & AHKS\flushot.txt, %LINENUM%
If ErrorLevel
{
break
}
Else
{
Loop
{
FileReadLine, MRNc, E:\AHK & AHKS\Billed65+Flushots.txt, LINENU
StringTrimRight, MRNc, 11
If (MRN != MRNc)
{
LINENU++
Match = 0
}
If (MRN == MRNc)
Match = 1
If ErrorLevel and Match = 0
{
FileAppend, MRN, E:\AHK & AHKS\Unbilledtester.txt
LINENU = 1
}
If (Match = 1)
GoTo Lab2
}
Lab2:
Loop
{
FileReadLine, MRNc, E:\AHK & AHKS\BilledAdultFlushots.txt, LINENU
StringTrimRight, MRNc, 11
If (MRN != MRNc)
{
LINENU++
Match = 0
}
If (MRN == MRNc)
Match = 1
If ErrorLevel and Match = 0
FileAppend, MRN, E:\AHK & AHKS\Unbilledtester.txt
If (Match = 1)
GoTo Lab2
}
LINENUM++
}
}
UPDATE!!!!!!!
Alright, so I grabbed your code, and I've been trying to run a reverse check. You check the associative arrays of the Adult and Senior flushot text files for the MRNS in flushot.txt, then if not found they're added to unbilled. Below are several of my attempts to reverse that, and check for the MRNs in Adult and Senior in flushot.txt, and if not found, to add it to a file called notrecorded.txt so I know what people got flushots and the MA who didn't record it (by Primary Care Provider).

I think you were on the right track by creating an output file rather than deleting lines. Text files are usually treated as streams, not fixed-record-length data files. Deleting lines is error prone and not efficient; you'd have to compact the file somehow.
How big are your files? If there are only a few thousand patients, I would just load everything into associative arrays so we can use keyed lookups.
Program
^L:: medical_run()
medical_run()
{
root_dir := "E:\AHK & AHKS"
fname_input := "flushot.txt"
fname_backup := "flushot_old.txt"
fname_temp_output := "Unbilledtester.txt"
fname_billed_adult := "billedAdultFlushots.txt"
fname_billed_senior := "billed65+Flushots.txt"
SetWorkingDir %root_dir%
FileDelete %fname_output%
adults := {}
seniors := {}
unmatched := {}
loop READ, %fname_billed_adult%
adults[A_LoopReadLine] := true
loop READ, %fname_billed_senior%
seniors[A_LoopReadLine] := true
loop READ, %fname_input%
if !adults[A_LoopReadLine] && !seniors[A_LoopReadLine]
unmatched[A_LoopReadLine] := true
