csh problem with while
Hello this my first post, so i hope you help me

Code:
	
echo -n "Choose which square you want to hit of PL2 grid "
	set pl2_square = $<
	set i = 1
	while ($i <= 6)
		if ($pl2_square == $pl2_ships[$i]) then
			$pl2_ships[$i] = x
			echo ""
			echo ""
			echo "PL1 has hitted a square of PL2"
			echo "PL2 ships are $pl2_ships"
			echo ""
			echo ""
		else
			echo ""
			echo ""
			echo "PL1 has hitted NO square of PL2"
			echo ""
			echo ""
		endif
		@ i ++
	end

I want this code to iterate on the elements of pl2_ships but it seems to iterate only on the first element not the remaining five. I want to know what is my mistake.

OUT OF BOUNDS QUESTION: Who is this forum belong to?
because in one of the posts I saw my doctor name "dr.sallay"

Hi.

I suggest you remove the first "$" from:
Code:
$pl2_ships[$i] = x

so that you have:
Code:
pl2_ships[$i] = x

Best wishes ... cheers, drl

Standard advice: avoid the csh family for scripting; use Bourne shell family instead ( sh, ksh, bash, zsh ).

If you are saying that the correction does not solve your problem, then saying "not work" is not enough information for us to help you.

Please post the shortest complete example that does not work and post the output plus complete error messages and the output that you think it should produce ... cheers, drl

now it woks I replaced $ in $pl2_ships[$i] = x to "set"
The final statment is:

set pl2_ships[$i] = x

Thank you drl for your interacting with my problem
