call: how many parameters?

[Petr M. <mi...@ph...>]

Currently, inside bla.gp called like

	call "bla.gp" one two 3 4

it is not possible to determine how many parameters were passed into it.
The only way seems to be a global variable like

	params=4; call "bla.gp" one two 3 4

and to use

	if (defined(params) && params==4) ...

supposing caller set the value correctly.

I propose to add "variable"  $#  which will be set to number of available
$0, $1, ...

What do you think about? Could someone add it?
