goes something like this (sample from DeltaTime())

code:

---

;FUNCTION         DeltaTime()
;
;AUTHOR           Jochen Polster (jochen.polster@gmx.net)
;
;ACTION           Calculates the time difference between two given times
;
;SYNTAX           DeltaTime(Start,End)
;
;PARAMETERS       Start (Required)
;                  -  String value representing the starttime
;                     Format hh:mm:ss[:ms]
;
;                 End (Required)
;                  -  String value representing the ending time
;                     Format hh:mm:ss[:ms]
;
;REMARKS          Highest possible delta Value is 23:59:59:999 !
;                 If the diff gets higher , the result will be incorrect.
;
;RETURNS          The difference between Start - and Endtime in 'hh:mm:ss[:ms]'
;
;DEPENDENCIES     None
;
;EXAMPLES         call "PATH\DeltaTime.udf"
;                 $start = @time + ':' + @msecs
;                 for $i = 0 to 15000
;                 	$ = @scriptdir
;                 next
;                 $end = @time + ':' + @msecs
;                 ? 'Start time  : $start' ?
;                 ? 'End time    : $end' ?
;                 $Duration = DeltaTime($start,$end)
;                 ? 'Duration    : $Duration' ? ?
;
;                 $start = "21:59:59" ? 'Backup Started  : $start' ?
;                 $end   = "01:00:01" ? 'Backup Ended    : $end' ?
;                 $d = DeltaTime($start,$end)
;                 ? 'Backup Duration : $d' ?
;
;                 get $k

Plus we should have an udf-internal-variables convention , maybe just like Richard once used :

udf internal starts with $__ or something like that
