If you want to allocate buffer for strings, you have to use "rb" directive:

Code:

Text rb 1024   ; allocates (reserve) 1024 bytes for string processing.

Also, you have to put the terminating zeros at the end of the strings you create with the program.
Of course if you need only string constants, you can define them using "db":

Code:

TextConst  db  'Some text", 0
