[REBOL] SV: Re: Func, why does it remeber previous data?
From: micael:gullmes:telenordia:se at: 11-Nov-2000 0:06
Hej Andrew,
Thanks for the hints, I changed according to your suggestions.
But the function still gets incorrect data, any other ideas?
---
find_stuff2: func ["Find stuff in data_block"] [
tail_data: make string! 0
tail_data: ask "what data do you want to find after ACDC? "
probe data_to_find: make string! 0
probe clear data_to_find
probe data_to_find: #{ACDC}
probe append data_to_find do rejoin ["#{" tail_data "}"]
result: make block! 0
clear result
foreach data data_block [
if find data data_to_find [
append result data
]
]
print rejoin ["Found " length? result " containing " data_to_find]
]
But I still get the same fault:
>> find_stuff2
what data do you want to find after ACDC? 01
#{ACDC}
#{ACDC01}
Found 2 containing #{ACDC01}
>> find_stuff2
what data do you want to find after ACDC? 01
#{ACDC01}
#{ACDC0101}
Found 0 containing #{ACDC0101}

Use:
tail_data: make string! 0
instead.
Think of ":" as being:
Set the word to the left to _POINT_ to the string at the right.
So this:
tail_data: ""
actually means:
Set the word "tail_data" to this particular empty string. It's like
assigning a pointer in C/C++, OK?
The same thing applies here:
> result: []
Use:
result: make block! 0
instead.
