RE: date validate

[Michael_Schutte@xxxxxxxxxxxx]

Why wouldn't you validate that YEAR was specified before allowing the page
to be submitted?

You're right, garbage in, garbage out.  To me, the YEAR check should be
done interactively on the page, not in a CGI process.

I won't go .net on you, as I don't use it here.  I don't know enough of it.
But JavaScript can be used to test the value. :-)

Always, it depends...

What do you do when you receive date input from a web page? Suppose I have
separate fields for the month, day, and year. The user types in the month
and day only. All TEST opcode operations will fail. How do I test the date?

I did something similar with the express purpose of validating dates from
web pages. That way, if the user puts in just the month and day, I can
default in the current year.

The problem I have with the TEST opcode is I need to know the date format
to
test. Now depending on how the date input fields are set up, that could be
easy or difficult. I prefer to use separate input fields for better
control.
An all-in-one field that can be used in .net could provide some confusion.

Don't go all .net on me, either. Yes, the date validator in .net is helpful
and nice, but don't forget the mantra for web applications: don't trust
user
input. Don't rely on the .net validator to ensure your program has valid
dates.

We don't know the OP's application target (5250, web), but having a more
robust and flexible validation routine than TEST can't hurt, for the
reasons
Bill mentioned.

My opinion is that it's a waste of time to go through all that trouble.
Making a mountian out of a mole hill.  If all you want to do is test the
date value in a character or numerical field, then just use the TEST
function.
