Searching for differences in text file

Searching for differences in text file

Searching for differences in text file

I have a ten sentence *.txt file that I want to search and find any differences in the individual sentences. The sentences are sequential. I've coded successfully to find the first mis-matched sentences, but can't work out how to continue searching for other mis-matches. What I want to do is continue the search onward from the first mis-matched line already found. Heres an example of the text file --
Now is the time to come to the aid.
Now is the time to come to the aid.
Now is the <b>slime</b> to come to the aid.
Now is the time to come to the aid.
<b>New</b> is the time to come to the aid.

RE: Searching for differences in text file

Open the text file and establish two pointers at the beginning of the file.  Iterate through the file til eof, moving the pointers as needed.  (It's been a long time since I programmed in BASIC)


FUNCTION checkLine($line)
  'function to compare $line to $text"

$text = "Now is the time to come to the aid"
RecLen = 35
OPEN "file.txt" FOR RANDOM AS #1 LEN = RecLen

curLine = 0
badLines = 0
   LINE INPUT #1, $line
   curLine = curLine + 1
   IF checkLine($line, $text) THEN
      badLines = badLine + 1


PRINT "There are ", curLine, " lines total.  ", badLines, " of which are wrong"

RE: Searching for differences in text file

Do you want to identify if the lines are different (that's easy) or do you want to print out the actual differences in each set of two lines?
