	I'm having trouble with nesting of csh "if-else-endif". In the following

    ----------------------
    #! /bin/csh				{
    set x=1				    x=1;
    if($x == 1) then			    if(x == 1){
	    set y=2			        y=2;
    else				    }else{
	    if($y == 2) then		        if(y == 2){
		    echo "line 1"		    printf("line 1");
	    else			        }else{
		    echo "line 2"		    printf("line 2");
	    endif			        }
	    echo "shouldn't get here"	    printf("shouldn't get here");
    endif				    }
    echo "finished"			printf("finished");
					}
    ----------------------

You problem is due to the fact that only one 'endif' is needed.  The 
documentation on the csh states:

	if (expr) then
		....
	else if (expr2) then
		....
	else
		....
	endif

	Any number of else-if pairs are possible; only one endif is needed.
