- String displayed on screen
- HL points to character after terminating zero of string

None
Comments
Since HL points to the character after the terminating zero of the string when the call is finished, you can put multiple strings in a row and display them all with calls to PutS. See the example.
Example
ld hl,0 ld (curRow),hl ld hl,string1 BCALL(PutS) BCALL(PutS) ;hl points to string2 at this point BCALL(PutS) ;hl points to string3 at this point ret string1: .db "This is a string ",0 string2: .db "This is another string ",0 string3: .db "Yet another string...",0
All three strings will be displayed in order, starting from the top-left corner of the screen.
