Hi !
Today, my question is : "How do you write a large text on the 8th line ?".
I add that I'd like to write this with this flag enabled : set appTextsave,(iy+appFlags)
I wrote this :
Code:
B_CALL(_homeup)
ld hl, 0800h
ld (curcol), hl
ld hl, label
B_CALL(_puts)
But it doesn't work and writes on the FIRST line !!! o_O 
How would you do to write on the 8th line with this mode (which permits to write large text on the "graph screen") ? Do I have to enable the following flag : "textscrolled" ? If so, How could I do it ?
Please answer ; it is really important !!!!
Thx
Edit : Oh, and please give me something less "heavy" than :
Code:
B_CALL(_homeup)
B_CALL(_newline)
B_CALL(_newline)
B_CALL(_newline)
B_CALL(_newline)
B_CALL(_newline)
B_CALL(_newline)
B_CALL(_newline)
 thx

Sure simple enough.
bcall(_homeup) places the cursor at (0,0) on the homescreen so not entirely useful. Unless you don't want to specify coordinates and only write in the first line.
Second of all you are loading the 16 bit register into the wrong area. CurRow comes before Curcol in memory.
Third. You must switch the order of the coordinates. Column first then row. As the will be reversed when they are loaded into the ram area.
Fourth. The TIOS only writes to the 7th row(this is the last line) coordinates in asm are 0-7 for rows and 0-15 for columns on the homescreen.
ld hl,0007h
ld (CurRow),hl
ld hl,text
bcall(_puts)
ret
text:
.db "Last Line",0 |

OK, it works, thank you
For the second and the third points, I think I mistook the registers for pencol/penrow. |
