On-line error parsing tool

Every now and then, someone on this list asks "what does this error
mean", posting several lines with mysterious numbers. Now you don't
need to ask anymore... (but if you really want to, you still can).
I have created a little on-line error parsing tool for Runtime
Revolution. Read on below, or go straight to the website at <http://runrev.info/error.html
Once in a while, you may run into a less-than-obvious problem, while
programming in Revolution. In these cases, you might see an error
message of the form (the code may consist of many lines):
Type: Chunk (can't find stack)
Object name: Button
Line:(row 7 col 11)
Type: start (can't find object)
Object name: Button
Line:(row 7 col 1)
Hint: Click Me
If you have no idea what causes the error, it may be useful to be able
to parse the error.
Parsing errors may also be useful if you have a try-end try control
structure in your script. You might use such a control structure if
the circumstances under which your script will run are unpredictable.
These circumstances include a script that is distributed as a library
amongst developers or a software product for end-users that needs to
be installed manually.
Your script might look like this:
start using stack "Foo"
--> error if not available
put myErr into url "file:C/log file.txt"
Now, if an error occurs, you need to know why. You can post the
contents of the file "log file.txt" into the form above and parse it
into a readable error message.
If you want to try it right-away, just copy the two lines of error
codes above, paste them into the form on the website, and press the
button below the field.
If you would like to build this feature into your own stacks, Economy-
x-Talk has a shareware library available that will allow you to do so.
This library can be downloaded at <http://economy-x-talk.com/developer.html
>. Note that there is also the error reporting feature in the
standalone builder, which is often, but not always, sufficient.
