just wanted to ask if there's a length limit the
AddFormField method accepts as a value?

Anytime I try to use the method with string more than
4096 bytes long the message box pops up with

"Format '%s' invalid or incompatible with argument."

So I'm looking for some tip. I was looking all over the
docs online / offline with no luck. Tracing the code
ends up in sysutils.hpp function: FmtStr where buffer
is declared as

Buffer: array[0..4095] of Char;

My guess is that's the cause, but how to make the
AddFormField method to accept strings longer than 4096 chars?
