The current apm code will check the if the values are valid when the user prints all the information. It does not however check single ones, such as if the user does apm -l. apm -l could lead to a result of -1, which is not an error but an invalid value. The same goes for the rest apm -as etc. The patch will validiate them, and print them depending on outcome.
