String replacement in batch file

We can replace strings in a batch file using the following command

set str="jump over the chair"
set str=%str:chair=table%

These lines work fine and change the string "jump over the chair" to "jump over the table". Now I want to replace the word "chair" in the string with some variable and I don't know how to do it.

set word=table
set str="jump over the chair"
??

Any ideas?

You can use !, but you must have the ENABLEDELAYEDEXPANSION switch set.

setlocal ENABLEDELAYEDEXPANSION
set word=table
set str="jump over the chair"
set str=%str:chair=!word!%
