[REBOL] Re: Rebol for real world applications

From: rotenca:telvia:it at: 20-Nov-2003 0:54

Hi Sabu, Memory is auto-recycled. You can force recycling with the recycle function. You can test the memory allocated by your program with system/stats You can have an idea of memory used by some code with these routines: http://www.rebol.org/cgi-bin/cgiwrap/rebol/search.r?find=mem2

No.
> pp: [] ; global variable. Is this needed?
No. Non locals are made globals in Rebol when you load a file.

You should use load/all. To-block works, but it does not load words in the global context. Un-loaded words are buggy in Rebol and can lead to crashes.
> [ return false ] > [ > cfg: make object! pp > clear pp; > return true > ] > > ]
your function can become: loadCfg: func [cfgfile][ not error? try [ cfg: make object! load/all cfgfile ] ]
>> loadcfg "a: 2"
== true
>> probe cfg
make object! [ a: 2 ] You should know that make object! executes the body block (the loaded block), so it is not secure. --- Ciao Romano
