Yes, can't open them in WinXP.
No, yes you can.
read %"Hi%there.txt"     <-- this filename works

yes, but load mold %"Hi%there.txt" does not

>> load mold "Hi%there.txt"
== "Hi%there.txt"

what version of rebol, what os ?

no, sorry, you're right. I missed the initial %
Rebolek

I think % should be automatically translated to %25 (like space is 
translated to  ) to prevent these problems

It does not mold into a loadable string. --> RAMBO.

well, that's really strange. see this >>
>> load mold to file! "[s-:-a]"
** Syntax Error: Invalid email -- %[s-:-a]
** Near: (line 1) %[s-:-a]
>> load mold to file! "[aas-:-df]"
== ª[s-:-df]
everything in range from "aa@.." to "ff@.." produces the second result

Add this information with the link to #3189 to your report. They 
should insert it into the original bug report.

these ways can be used to circumvent the filename character problems 
if needed:
load {%"aaa%aa"}
load "%aaa%25aa"

how to catch following error? error? try [to-date 29-Feb_2006]
ok, putting date in a string helps ...trying to catch leap year ...
I don't like it - why rebol parser interrupts me so fast?

petr, in the above case (without the quotes), the error happens before 
rebol gets to evaluate the TRY.
you need to put the LOAD or DO that are loading that code in a try 
block.

it does not seem to work:

error? try [load 29-Feb-2006]
I would prefer 29-Feb-2006 error, as well as e.g. error? try [load 
380.250.250] being a bit more relaxed in interpreter ...
how can I catch such syntax errors?

what is your problem?

error? try [load "29-Feb-2006"] ; == true
Pekr

the problems is uncatchable error
I am not talking about string ....
I am not sure I can meet with such situation in real-life :-) I just 
got asked by Bobik. The thing was, that in sqlite date field there 
can be invalid date. Now I am not sure how is the conversion done, 
if via string, but if you simply type such invalid date in console, 
it can't be recovered, and that is my objection in general ...
shouldn't we be always able to recover from whatever error happens?

To be executed, a script is loaded in a whole. So each values is 
loaded/binded and your error appears at this time, not while the 
expression is evaluated.
Pekr
26-Jun-2006
[4944]
do you mean that I can catch the error during load? but why loading 
value itself fails?
Graham

what uncatchable error?
Pekr
26-Jun-2006
[4946x2]
try to type in console 29-feb-2006 ....
although it is invalid, I thought that by error? try [29-Feb-2006] 
I will be able to recover eventually, which is not the case ...

Doesn't like the 29-Feb-2006 as a date string
date type!

Does not like 32-may-2006 too. Isn't this more a feature than a bug?
error? try [29-Feb-2006]

 is "word! word! [what-is-this?]". Reol has no idea what to do with 
 "error?" at that time.
Pekr
26-Jun-2006
[4956x2]
well, but Volker, anyway, we got to state, where we have non-recoverable 
interpreter state, don't we?
I know the date is invalid, but .... the same goes for tupple, e.g. 
380.250.250

** Syntax Error: Invalid tuple -- 380.250.250
** Near: (line 1) 380.250.250
you are not at interpreter state at that time. think of 'load finding 
an error at compile-time.
Pekr

I know, I just don't like the fact, console is not safe from such 
errors ..

Thats why ladislav puts the date in a string. compiled later.
how should it work instead?
Pekr
26-Jun-2006
[4963]
ok, can we meet with state, where your app returns directly such 
invalid date? e.g. mentioned link to sqlite date field?
