[REBOL] Core 2.5.2 help

From: ingo::2b1::de at: 7-May-2002 23:54

Hi Rebols, nice to have a help on paths, now, but I'm kinda accustomed to do things like
>> help system/stats
SYSTEM/STATS is an integer of value: 4039648 and get:
>> help system/stats
USAGE: SYSTEM/STATS /pools /types /series /frames /recycle DESCRIPTION: System statistics. Default is to return total memory allocated. SYSTEM/STATS is a native value. REFINEMENTS: /pools -- Returns: width units free-units units-per-alloc segments mem-in-use /types -- Returns: Datatype count /series -- Returns: total blocks strings other avail free expansions /frames -- Returns: total used unused free values-total /recycle -- Returns: count series-total series-last frames-total frames-last ballast So here s my help patch updated for 2.5.2. ------- start patch (watch for line wraps) ------ [REBOL [] help: func [ "Prints information about words and values.
