sorry for the question I am a total beginner in programming and probably this is very easy for someone who knows what to do:

I need to create, into a txt file, a serie of links with incremental numbers, for example I want to keep a certain part "fixed" and a part has to change; for example imagine this:

<http://user:password@website.com/members/sets/001/somethingfixed-001.zip>
in the text the following lines should be:

<http://user:password@website.com/members/sets/002/somethingfixed-002.zip>
etc..

I think there must be a way to generate those where I could specify, create the link keep the fixed part equal in every line and then incrementally put 001, 002, 003, up to the point i need it.

it could be awesome if I could create a .bat file that would ask me: what is the initial link, what is the part to be fixed and what to change.

I'd do the program like this:

insert the first link, and I paste it.

then it asks me for what is the fixed part and I put:
.../members/sets/X/somethingfixed-Y.zip

what is the range for the variables X and Y?
starting number? and I put 001 and then it asks me what is the end number? and i put 150
and it generates the links in the txt file so that I can use them.

Hope it is clear.

Cheers
