[REBOL] Trapping an error

From: Steven:White:ci:bloomington:mn:us at: 7-Nov-2003 9:05

I am wondering if someone can tell me how to trap a particular error. Yes, I have read the GDM, on "try" and "attempt," but they don't seem to be the correct answer. (It is quite possible I don't fully understand the documentation.) Here is the situation: I have a "configuration file" for a script. The configuration file is itself a little REBOL script that just sets the values of some words, for example REBOL [ File: %config.r ] HELP-FILENAME: %XXXXXX In the main script, I set default values for those things in the configuration file, and then "do" the configuration file to over-ride the default values. For example REBOL [ File: %main.r ] HELP-FILENAME: %YYYYY ;;; set default value do %config.r ;;; override default value This works just fine EXCEPT if I put an incorrectly-formatted file name in the configuration file. If the file name in the configuration file is bad, then when I "do" that file the script crashes. Is there a way to trap that error before the REBOL interpreter does, so that I can handle the error in my own way? Thank you.
