You don’t need DFILE just built the string and print the string.
Edit: you need to poke the string. PRINT skips the bit6 codes.

I have altered the QUARACTER-generator

Controls are still QAOP and SPACE but you see the ascii-value of the character
and you can directly change the character in ANY other value simply by pressing that key.
When you need QAOP or SPACE you press a close key and use LEFT/RIGHT to make the right value.

I've just tested this on the Lambda 8300 and was very curious about the result. Because the Lambda 8300 only supports text mode.

It gives a new graphics mode on the Lambda 8300. Yes! But it is a little different than on the ZX81.

We need to find out why so we can predict our graphics.

Now we have found, that the Lambda 8300 displays the same characters as the ZX81, if an extra regular text line is below.

Can you then port the QuarGen software to Lambda 8300, or maybe release the source? EightyOne and JSZeddy will help you test the software, as they currently is the most accurate emulation we have.

I will give you the source.
And I can make a port of MUSHROOMMAN too.

Incredible!

First of all… you only need LD H,D and LD L,E only once on every line.
a line may moke like this
Db “ld h,d”, “ld l,e”, 30 spaces, 118

To do a display you then place a character somewhere on the line and a second, third and fourth on the same position a line lower.

Horizontal movement is 1 position left or righ5 but check that you do not overwrite the opcodes for de ld h,d, ld l,e and halt in that line.

For vertical movement you need to go down 4 lines.
