Error fuzzy logic

 [1/3] from: ptretter::charter::net at: 26-Aug-2001 8:10

Anyone ever have problems with the error? logic checking. The following for example: ------------------------------------------------------------- if connected? [ if error? error: try [send [ptretter--charter--net] read %log.txt][error: disarm error] ] ------------------------------------------------------------- my fix to the problem at this point was to build a function for this process - here is the complete section of code: forever [ wait 60 rtime: now/time if rtime > (ctime + 1:00) [ ctime: now/time if connected? [if error? error: does [try [send [paul--tretter--charter--net] read %log.txt]][ error: disarm error save %errorlog.txt mold error ] ] ] ] Just curious if anyone knows whether there actually is a bug with the Try function or if its an error with the Error? logic! datatype. The second example when putting 'Try into a function appears to work. The other one did but would crash often giving the message that "error has no value". Paul Tretter

The problem ist not the "error?", but the "error:" Send will, when it does not fail, return "null" and this causes the "needs a value" problem when trying to set the word "error:". The sollution: if error? set/any 'error: try [....] set/any allowes to set null to values, too. An other sollution would be: if error? error: try [.... none] Your example looks not like it will send the email. Because you are producing a function and check it, if it is an error. This is not true, because function! <> error! . So you will not run the if-body

Paul: I have noticed that there is a difference in most of the logical functions including IF and EITHER than one might be used to. I simply consider any options until I make it work -then I write my own FUNCTION that makes sense to me. You might call that an error, I'm impressed with the logic of writing my own functions -it works for me. The answer is in testing the code as you go. John At 08:10 AM 8/26/2001 -0500, you wrote:
