Problems with export CMD

[compsystems]

If you run for example inputv1a for first time x -> 0, then if you enter a value of 8, and then you close the program, the next execution appears x -> 8 and not x -> 0

It becomes zero when you recompile, for example when you edit the source code (prg editor calculator), or from the program editor of HPconnKit this is correct x -> 0

PHP Code:

export x:=0;
export inputv1a()
BEGIN  
  input( x );
  return "Done";
END;
