It should be possible to write such a function pretty easily.  
Here is some pseudo-code.

function which(exename as string) as string

	dim paths as new String[]
	dim path as string
	dim dirresult as new String[]

	paths = Split(Application.Env["PATH"], ":")
	for each path in paths
		dirresult = dir(path, exename)
		if dirresult.count > 0 then
			return dirresult[0]
		end if
	next

	return ""

end
