Call GetAllPids$()$ and GetNameByPid$()$ to print out all pids and their names.

Set pid to $1.$ Call GetNameByPid$()$ and print out the name of pid $1.$

Set name to "Lab$1".$ Call GetPidByName$()$ to get the pid of Lab$1.$ Print "Lab$1"$ and the pid of Lab$1.$

Set name to "Lab$11".$ Call GetPidByName$()$ to get the pid of Lab$11.$ There should not be a process called Lab$11,$ therefore this should test your error message generation system.

If any errors are generated in the calls to these functions, the error must be printed out by a call to the function GetErrorMsg$()$ with the error number as an argument.
