If vertical plot limit is 191, what is the horizontal plot limit?
H=$1F = 31 (<=30) 
V=$BF = 192 (<=191)
Code: Select all
Lb4106:
LD A,$1F
SUB C
Lb4109:
JR NC, Lb4110 ; [$4110:16656]
Lb410B:
CALL Lb4097 ; [16535]
RST 08H
.db $10 ; RST8 Arg: Error Code:'H'
Lb4110:
LD A,$BF
SUB B
RET NC
Lb4114:
CALL Lb4097 ; [16535]
RST 08H
.db $1E ; RST8 Arg: Error Code:'V'
Lb4119:

All eight pair got connected, as documented.
Now, can this software invert the hi-res display?

Horizontal coords are based on byte positions while vertical coords are based on pixel rows. The max horizontal pixel coord is 255.
More info about SHREB can be found here...

Greg,
Attached a searchable version that includes an SHREB upgrade. I found no mention of upgrading in the manual, so could SEHR.P be upgraded to v3.00, that is fully functional (w/F-SAVE/64-column) . . .
THX!

Greg,
Please let us know when you figure out how to use Tom's SE, but 1st,
splash screen gets generated, then HANGs w/key press.
Very finicky!

Greg,
It appears that the P file format is very unstable when the file exceeds 16K. Here is an example where EO can generate only a valid wav file. Either a P or TZX format of the same program freezes. To launch this SHREB file, GOTO 200, then hit '9' and wait to see graphic.

Greg,
The SHREB version 3 appears to handle Tom's SE graphics, but not regular text. If you know the subtlety between 2 and 3, please enlighten

This is a problem with ZXPand not the program. When generating standard ZX81 type characters SHREB expects to find the character patterns at $1E00, which are are no longer there because of the ZXPand overlay ROM. Pseudo-hi-res programs also have a similar problem.
Try loading the program with the /x option.
