I know the second 9 is 9 bytes of space in front of 9, 0 is what mean

CodePudding user response:

Er, definition of 2 bytes of data, an initial value of 9, one is zero

CodePudding user response:

Define a character buffer, the maximum number of characters of 9, the current actual type the number of characters to 0, the initialization (nine character space? Said no value),
Equivalent:
Maxlen db 9
The action the db?
Words db 9 dup (?)


You can see your definition of 9,0,9, as to how much space each character, look at you to define data types, db is each character occupy 1 byte, is here,
Another STR is assembly reserved words, you can't use, you should see an error,
