Puzzle #1: In the Eiffel library class DATE there are both "make_now"; and "make_now_utc" features (even though there seems to be no mention of "make_now_utc"...
How do you construct and execute Eiffel classes from C#? I've managed to get C# to see the class. indexing description: "Hello World example with Eiffel for...
Dear, I think that when you make DATE object with make_now_utc the date is UTC (GMT) and when you make it with make_now the date is your local date. Say, if...

Dear Paul, ... It is working fine although I haven't tested it with "big" numbers (those who do not fit into INTEGER). Thank you. Yours sincerely, Robert...

Brian Heilig writes: Also, `not (is_digit)' will only tell you if the CHARACTER is not in "0123456789". This means special characters (e.g. !@#$%^&*() etc.)...
`is_integer' is a query on a STRING while calling `item' on a string returns a CHARACTER. Class CHARACTER has the query that you need for this. Regards Chris...

Hi Ben, ... Convert the CHARACTER to a STRING using `out', and then call `to_integer'. Alternatively you can use `code' to return the ASCII code of the...
Hi, Ben. You can ask a STRING like "1234" if it is an integer or not. But ask a CHARACTER if it is_digit. You can use substring (4,6) to get just characters 4...
... Hi, Ben. You can use CHARACTER's code query to get the ASCII value (an integer) for the CHARACTER. The expression ('0').code gives you the ASCII value (48)...
Ben - You asked "why does is_integer work sometimes...?" The answer is that 'item' of a STRING returns a result of type CHARACTER, and is_integer is not...
Unfortunately, as you have observed, CHARACTER does not have a feature that converts the character value to an integer value. Instead of playing C-think style...

In 5.3 we have added `make_now_utc' in DATE_TIME and TIME class. But in the case of a DATE, this is normal that the time is by default set to `12am'. Manu...

Dear Manu, ... I do not understand why create utc.make_now_utc should set the time to 12 am when UTC is thicking like any other time. For example I am writing...
DATE is the class for dates only. TIME is the class for time only. DATE_TIME contains both. Since the OS represents date and time as a single time_t value,...
