Bash get value of loop var

Question

I want to create files Foo{A..Z} and insert "This is file [A-Z]" in the files.

Example:
FooG should contain the text
This is file G

First I need to create the files:
touch foo{A..Z}

Then I need to insert the text i want into all files:
echo This is file{A..Z} > foo{A..Z}

This won't quite work, as I need the current loop variable value
(which is somewhere between A and Z) from the foo{A..Z} from the line above.

No need to create the files first, just use a loop:

for i in {A..Z}; do
    echo "This is file $i" > "Foo$i"
done

Now $i can be used to refer to the letter to be inserted, as well as part of the filename.
