remove_from_list and removeItemInList don't seem to be working

by inference, the cause is probably me, but here it is, neither  remove_from_list and removeItemInList  seem to be removing the requested item from the list

  • neutral

typeof list1 =[I r1];;
typeof list2 =[I r1];;

fun remove_from_list(l,p)=
 if l==nil then nil
 else let l -> [a nxt] in
  if a==p then nxt
  else a::remove_from_list nxt p;;


fun removeItemInList (list, item)=
	if list == nil then
		nil
	else
		if item == hd list then
			tl list
		else
			(hd list) :: removeItemInList tl list item;;
			
fun main()=
   _showconsole; 
   set list1= 2::8::561::591::nil;
   set list2= 2::8::561::591::nil;
    _fooS  "we are starting with list1 below:";
    _fooIdList  list1; 
    remove_from_list list1 561;
    _fooS  "the list after remove_from_list is below";
    _fooIdList list1;
     _fooS  "we are starting with list2 below:";
    _fooIdList  list2; 
    removeItemInList list2 561;
    _fooS  "the list after removeItemInList is below";
    _fooIdList list2;;

This is normal. The returned list is your result.

set list1 = remove_from_list list1 561;

and you are happy smile
