Re: Regarding File Source Block Funtionality

[CEL]

Dear Shivam,

the mailing list archive shows no record of you ever contacting this
list under the subject "Regarding File source Block Funtionality"[1] or
from someone named Shivam at all[2].
This, together with the fact that we're basically participating on this
list in mostly unpaid time might explain why you've never heard from
us.

First of all: it makes no sense calling an output file *.txt. It's not
text, see our FAQ [3].

It's not clear what you'd want to do here: The slider is not a display
element. Your requirement doesn't make much sense. What's the *purpose*
of all this?

Best regards,
Marcus
