forall error

 [1/8] from: charliew::drte::com at: 22-May-2001 10:05


When I do a forall I get this error. Thanks in advance for your help.. Charlie ** Internal Error: Stack overflow ** Near: not tail? get word get: func [myVar] [ forall myDB [ rec: first myDB if rec/fType = myVar [ remove myDB ] ] ]

If you have a minute, would you try this alternative? get: func [myVar /local walkDB] [ walkDB: myDB while [not tail? walkDB] [ rec: first walkDB either rec/fType = myVar [ remove walkDB ][ walkDB: next walkDB ] ] ] I don't have time to test it right now, but I suspect that your problem comes from mutating the same series that FORALL is trying to walk through. The only thing I'm doing different in the snippet above is explicitly managing the remove-or-step process. -jn-

Hey Charlie: `get is a rebol word, I believe. It looks like you have some major recursive activity going on there.... thus the stack overflow. You're "overloading" here, I think. I believe that others on the list can show you how to get around this, but I avoid overloading rebol words unless absolutely necessary.

If you don't have time to think about it, would you try this alternative? Wait until you do think before responding to email! ;-) -jn-

If you look at the error above, you'll discover immediately what the problem is. :-) (For Charles: you called your function GET. The word 'GET in REBOL is usually associated to the GET native function; FORALL wants to call that function, and uses the 'GET word to do so. But since you just told REBOL that the word 'GET is associated with your function, FORALL will call YOUR function instead of the native GET. Your function, in turn, will call FORALL that will call your function again and so on until you get a stack overflow.)

Reserved word bug? Nay, it's a feature! BTW Using an editor with up-to-date syntax highlighting helps tremendously to prevent this problem. - Michael Jelinek, who redefines "reserved words" when it suits him (adding refinements, etc) From: Charles Wardell <[CharlieW--drte--com]>@rebol.com on 05/23/2001 11:40 AM Please respond to [rebol-list--rebol--com] Sent by: [rebol-bounce--rebol--com] To: "['rebol-list--rebol--com']" <[rebol-list--rebol--com]> cc: Subject: [REBOL] Re: forall error Thanks alot, Not the first time that I have been bit by the reserved word bug..
