Another problem occured: -I can construct a filename an increment it always by 1 to get with [makefilename]. - But I want to make snapshots from a webcam by using [pix_write] and this object does already do an increment of the <basefilename>, which means adding <current#>. - Is there a possibility to switch this <current#> off. Or controlling it, which means just taking numbers from 0-100? thanks

what is the purpose of [prepend] here? couldn't you do that with [prepend $1( for exactly the same effect?

Guessing you mean [rm $1( I also often use [list prepend foo]-[list trim] (which is the vanilla equivalent of [prepend foo]) instead of [foo $1(, because, though for one single "$1" value it is exactly the same, I consider it (rather questionably) to be more elegant in that it works for messages of any length.

Consider:

(some number) | [list prepend set] | [list trim] | (some numberbox)

and:

(almost any message) | [list prepend set] | [list trim] | [my message box(

I just like the fact they look the same.

Note however that the letter is not 100% general: "foo bar" and "list foo bar" will both put "foo bar" into the message box.

Of course I don't know if Derek uses that for the same reason as I do :)
