Howdy,

I'm working on a script where I want to get hold of a particular string
and use it as a new name of a particular window.

What I've tried so far, although not successfully, is writing to
/dev/$winid/addr with the intention of then being able to read the
string found from the /dev/$winid/data or /dev/$winid/xdata.

acme(4) says,
addr        may be written with any textual address (line number,
               regular expression, etc.), in the format understood by
               button 3 but without the initial colon, including com-
               pound addresses, to set the address for text accessed
               through the data file.

Here's an example of what I tried.
echo '/[A-Z]+\![a-z0-9]+\![0-9a-z]+' >/dev/$winid/addr

Which results in an 'address out of bounds' message being generated.

How does one write to 'addr'? Clearly, the shortcoming is on my part.
I'm just not sure what it is that's missing.

Thanks.
