But what do you want it to validate?

What's acceptable...?

What's not...?

Hello Bobby,

It should accept nmaximum 500 characters in multiline text box "Mark

$(?s:.){500}$

should do it.

though if you want to count a carriage return + linefeed as one or as zero
characters you'd need to adjust it a bit.

Remember that this won't ensure that the maximum number of bytes never exceeds
500, Unicode will mprobably stump you there.
