+/* TODO -
+Bit of a problem, but I think it will go away once llGetSubString() is implemented.
+The problem is that Lua can't convert the string "0x" to a number, though it's fine with "0x0".
+In LSL any string that does not represent a number gets converted to 0 by a typecast.
+
+In other cases the LSL code is typecasting a string to an integer, but Lua can't coz it's not a real number in the string.
+
+Sooo, should actually implement that typecast.
+
+function  --[[integer]] channel()
+  return  --[[(integer)]] ("0x" .. _LSL.llGetSubString( --[[(string)]] _LSL.llGetKey(), -4, -1));
+end 
+
+function setBalls( --[[string]] cmd)
+  local  --[[integer]] ch=channel();
+  _LSL.llSay(ch+ix, cmd);
+end
