I'm working on a personal project, a multiplication quiz script for my kids. In it, the user's performance will be recorded and written to a file. After they've played it a little while, it will start to focus more on the ones that give them the most trouble-- that take a long time to answer or that they more frequently get wrong.
The information for each user will be written out to a file for future reference. The format will be something like:
where each trialx will look like:
YES/NO is simply the answer to the question, "Did the user give the right answer?" So, long explanation over... Here's what I'm wondering: What is the best way to append the most recent results to particular lines? Suppose that the user chooses to do a 3-question test and gets this output:
Then I want to take "YES,18,1.635" and append it to the "3,6" line of the file. Similarly, "YES,90,1.838" will be appended to the "9,10" line, and so on. What's your suggestion for the best way to do this from within a script? I can load the external file into an array, append, and write out, for example, but is that the best way? How would you do this? Please let me know if the question is unclear. Many thanks in advance.

Hi,
I have the following file,
ABC.txt:
ABC=123

so the same file ABC.txt should look as follows
ABC=123
#DEF=234
FGH=345
Sorry if its a... (6 Replies)
