You probably have noticed the .BYTE lines the past two lessons.

I've decided to move away from the classic 'design' and the usage of GO$1300 or GO$2000 or whatever,
and switch to another classic which is well known to practically everyone.

On Commodore C64 there is widely SYS 2061 or sometimes SYS 2064 used!

Well, sure enough, you can use that on Commodore C128 too.

I saw last video on YouTube, where a guy was explaining how to do it {C64} 
And he needed 40 minutes to explain the procedure.

We can do it under one minute, but some of you will probably need a few seconds longer.

STEP 1: Write BASIC lines
STEP 2: ENTER ML-Monitor with the Monitor command
STEP 3: LIST the BASIC start area M 1c00 1c58
---------------------------------------------------------------------------------------------------

Example BASIC lines:

10 rem (c) www.mzretro.ch
20 rem sprites >255
30 rem commodore c128
40 sys 7256

>01c50 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff:................



STEP 4: Make the listed BYTES {mandatory including the last three 00 00 00} EDASS-128 READY:
---------------------------------------------------------------------------------------------------

{ I am doing this in Notepad, Windows, by replacing " " {SPACE} with ",$" AFTER the separation of the
  16 BYTES in 2 x 8 BYTES, see this example below. 
  Put minimum 2 SPACES between the .BYTE and first e.g. $00, just like this example is showing }

.byte  $00,$1a,$1c,$0a,$00,$8f,$20,$28
.byte  $43,$29,$20,$57,$57,$57,$2e,$4d
.byte  $5a,$52,$45,$54,$52,$4f,$2e,$43
.byte  $48,$00,$2d,$1c,$14,$00,$8f,$20
.byte  $53,$50,$52,$49,$54,$45,$53,$20
.byte  $3e,$32,$35,$35,$00,$42,$1c,$1e
.byte  $00,$8f,$20,$43,$4f,$4d,$4d,$4f
.byte  $44,$4f,$52,$45,$20,$43,$31,$32
.byte  $38,$00,$4d,$1c,$28,$00,$9e,$20
.byte  $37,$32,$35,$36,$00,$00,$00,$ff

---------------------------------------------------------------------------------------------------

COPY the BYTE lines and PASTE them in EDASS-128 just like show here!

OF COURSE...

It doesn't need to be a 500 pages book, hehe...

This would do the job just fine:

As this is taking less space, you could choose lower start address e.g. dec 7200. $1c20
and save a few bytes, meaning gain a few bytes for the main program part!
