Question How to generate multiple lines in a text file?
Hello,
I want to create a file whose content is multiple lines of strings.

The string has the following pattern:

Code:
 
aaaa/bbbb/A-B.txt

A is a variable ranges from A1 to A2
B is a variable ranges from B1 to B2

Any ideas?
Thanks.

Thanks for the code, but the variable A I need should be more than 1000. Typing 1000 numbers in the script is not practical.
