If you look at the thread the poster referred to, you'd see there's already a way of getting rid of the output: !.echo -q <text>.
It's usually useful when making $regsub() substitutions or $filefile() loop with a fourth (command/@window) parameter, because we're not always interested in the numeric values returned by them.
For example,
alias remhtml {
; //echo -a $remhtml(<p>text</p>)
var %a
!.echo -q $regsub($1-,/&\S+?;|^.*?>|<.*?>|<.*?$/g,,%a)
return %a
}
alias flist {
; /flist
!.echo -q $findfile($mircdir,*,0,echo -a $1-)
}
For some reason, he doesn't like it. He wants an implementation of a new comamnd (or special prefix) which will evaluate the content and drop the output. Perhaps /nul or something.
