Is token replacement/removal within a delimited string possible within a batch file?

If I had a comma delimited string: a,b,c,D,e,f,g

Could I tell a batch file to replace, for example, D with h, leaving the REST of the string alone?

ThanksI suppose no one here has ever had a need for this. It is perfectly possible. You can easily use FOR to read the comma delimited string, and then write out the tokens again, substituting another substring for the 4th token.What I was hoping to avoid was having to deconstruct the string and rebuild it every time. The thought was maybe someone knew of a logical process or some command which could be used to rewrite a specific token in the string, sort of the opposite of what the For /F would do when it reads a specific token. Looking back on my initial post, I was vague, and I apologize. I'm just going to have to write a deconstruct/reconstruct process, which will work, albeit lengthy. Suppose I was just being lazy, hoping for an easier way.

Thanks again.Quote from: gregory on January 13, 2009, 02:44:55 AM

Why? This is the kind of task that computers are good at.

half of everything is work.

What's the other half?

why not use set ? easier i think
