in reply to Unexpected Output

For checking the length of an array,don't use $#arrayname because it won't give the number of elements in an array and it gives the highest index of the array which is number of elements - 1 in the array.If you want to check the length of an array, you assign an array to scalar, then it will give the actual number of elements in the array.There is one more problem in $#arrayname, it gives the value by adding the value of $[ with highest index of an array.In your script, if you change the value of $[ variable, then $#arrayname won't give the correct value.

[davido]: Exactly: SoPW. This isn't going to be solved easily in the CB.
[james28909]: in need "yesterday" and so on, to be absolute like "1" or "31"
[stevieb]: ...and throw some of your existing code into the equation as well, just so readers know you've given a try at it ;)
[james28909]: ok
[stevieb]: davido thanks for the link ;) I was being the typical lazy
[davido]: date parsing is hard. The more examples you can provide of the input (within reason) and expected output, the better.
[stevieb]: agreed. That's why I said at least a half-dozen. If enough of the different formats are present, the date/time folk may not have to request more. If they do, then at least there was a decent base to start with
[stevieb]: I do date and time transformations in both Perl and Python, but not frequently enough to not have to search for the format params etc ;)
