Hello all,

I am writing a batch file in DOS, one of its functions is to search through a file for a string of the format:

SOME TEXT WHICH MUST NOT CHANGE Version1.2 MORE CONSTANT TEXT

and replace it with:

SOME TEXT WHICH MUST NOT CHANGE Version1.3 MORE CONSTANT TEXT
or
SOME TEXT WHICH MUST NOT CHANGE Version 2 MORE CONSTANT TEXT

Depending on the values read from a different file.

I have found the function FIND which will find the entire line but I am not sure how to extract the Version and number and replace it.

FINDSTR also seems to almost do what I need but I having trouble making the final step and I cannot find any example which already have this done.

Can anyone help?
