Batch is interpreted line by line by cmd.EXE, batch is slow. Using external executables is always faster, they run from memory and don't need to be translated to machinecode. You could opt for another language like vbScript, that should be about 200 times faster here. Wonder if this is a little fas...

3rd party applications are OK if they are free, portable and reliable, so REGEXP apps like GREP are out. That confuses me as grep is free portable and reliable. I didn't want to add the grep dependencies to our server. I have a hard enough time convincing my boss to let me use stuff I find on the i...

Suppose you have a rather large text file and you need to format each line for consumption by another application. You could do a FOR loop through the file, arrange the data and ECHO it out to a text file simply enough ... for /f "tokens=1-14,* delims=:. " %%a in (%cDataFileTmp%) do ( @ech...

DOS is an old operating system. DISK OPERATING SYSTEM. What you mean is batch is old but in reality as far as scripting languages and shells go it is not even as old as CSH or TCSH or Korn for that matter.

It's old to me!

I know this is a very old thread; however, I couldn't resist the temptation to insert a couple comments here. Many, many years ago, when I was hired for the first time as computer programmer, my boss was worried about a critical section of a program that must generate a very important result. The k...

Was it one of my scripts or something that Ed said?

In any case, you're welcome.

Excellent! Thanks!

Quick question - does goto:eof do an implicit endlocal? It appears to do so. I was just looking at some of my code and wondering if I had to call endlocal before the goto:eof.

Haha hold on, you misread what I said Yeah, I do that a lot. I suppose that removal of the comments would tend to speed up the processing of long scripts - even double-colon comments which I understand are completely ignored by the interpreter. Double-colon comments don't work inside IF statements ...

Good. Commenting is good practice too. However I personally would use that as source, and have a working copy that's stripped and minified. No need on such a short script though. Well, it may not be needful for you but I have a mind like a steel sieve and considering that I am programming in DOS Ba...

Wow - that was like, amazing! You're explanation was a little verbose but a little playing around with it resolved the problem completely! Thank you so very much!

I did. It displays one screen of output at a time. I'm not sure how that helps me write a file faster. Sorry - I'm stupid, OK? I don't get it.
