replace string in dos

[pho01]

using dos command, how do I replace/delete a character from a string?

For example:

%strvar%="error found in "prod_4" procedure"
how do I remove the " char in the above variable so the variable can become:

%strvar%="error found in prod_4 procedure"

Thanks,
Phuong

Don't think there is a built-in command in DOS for this, but you can download grep or sed for DOS (perform a google search on Search and Replace in DOS) and you should be able to find a tool appropriate for you
