 ''NAME-PROCESS''
-Cosmetic function for labeling processes as shown on the LabLISP window, accepts one or two arguments. First must be string - the desired name. Second argument is optional integer specifying the process number, if not supplied, the active process is renamed. This function can be only meaningfully used on the active running process, to give information about reason for waiting.

 ''KILL''
-''SELF-KILL'' FIXME
+Function kills given process, needs one argument, the process number. Cannot be used on the active running process. Meaningful use is killing process stuck in an infinite loop. Returns ''NIL'' always.

+''SELF-KILL''
+This function kills the active running process, no arguments, returns ''NIL''. Although this might seem meaningless, this function is useful in mechanics for aborting script.
-these are unique LabLISP multi-process functions
+The last three functions are unique for LabLISP multi-process mechanics.
