I make my living writing LabVIEW which is drawn rather then written. I presume
this is what you mean by VPL.
This language would be impossible to use without a mouse.
Another language that used to compete in the same space as LabVIEW was HP VEE.
It would have also been impossible to use without a mouse.

Subject: Visual and text languages
I'm fairly new to the PP literature. Thomas's self-promotion led me to his
interesting 1996 paper on visual programming languages. "Overall, we believe
that in many respects VPLs offer substantial gains over conventional textual
languages, but at present their HCI aspects are still under-developed.
Improvements in secondary notation, in editing, and in searching will greatly
raise their overall usability."
As someone who does a lot of work in textual languages - in particular,
livecoding - I'd be interested to know what the state of the literature is on
VPLs, especially in comparison against text languages. I haven't been able to
find a recent survey, any recommendations?
(Also, as someone who has had RSI, I wonder about the accessibility of VPLs via
purely keyboard control...)
