I always use either "which foo" or "type foo".... one of those is 
a shell builtin and the other isn't, and for your purposes I'd 
use the one that isn't.

If you would rather do it without shelling out, you'd need to do 
something like

public function findprogram(prog as string) as boolean
dim found as boolean
dim d as string
found = false
for each d in split(Application.Env["PATH"], ":")
	if exist(d &/ prog) then found = true
next
return found
end

Untested, of course, but you get the idea.
