Hello list

I have doubt on TEXT data types... Checking my notes I see these ones:

TINYTEXT/TINYBLOB (2^8) 255 chars
TEXT/BLOB (2^16) 64K chars
MEDIUMTEXT/MEDIUMBLOB (2^24) 16M chars
LONGTEXT/LONGBLOB (2^32) chars

Well, my doubt consist on this... are these FIXED lengths for the text fields
or they have variable length that may grow up to that as maximum?

I require to store messages of variable length from 1 to 1024 characters, so
TINYTEXT is too short and TEXT is too large, so I want to know if it they
have variable length analog to the VARCHAR type and the client program only
ensures the messages to have 1024 length...

Thanks for your
