Hi

Hope this helps someone else :-)

I saw a post by Andy Dansby who writes at https://zxspectrumcoding.wordpress.com/

He has created a fast plot routine, (hellaplot), so I thought I'd try and convert it to a Boriel Basic (BB) subroutine, just for fun and learning - and as it was a single routine.

I had to do a little bit of reading, but also had to ask for help from the BB telegram community, as to begin with the code was crashing the emulator. Turns out it was a simple fix when you know how - FASTCALL was needed when passing parameters for ASM to use from a SUB routine.

Andy's code needs the x/y locations in DE, so I had to do a little bit to get them set up like this - I assume there might be some more efficiency if different registers were used as BB passes from the subroutine call, the first parameter into A, and the second parameter is the second item on the stack (the first being the return address).

When I started, xPos was the first parameter, and yPos the second (as I like x,y), but this meant to get them into DE, took another load (POP DE, LD E with D, LD D with A, compared to POP DE, LD E with A)

So some "non exact" timings - plot included as the library in BB takes about 15 seconds to fill up the screen with "points". Andy's one takes 5 seconds to do the same.

As far as Andy's code goes, I understand the comments, but not exactly how it works :-)

Anyway, code below :

SUB FASTCALL HellaPrint(yPos as UBYTE, xPos as UBYTE)
' HellaPrint prints an x,y pixel
' 0,0 is top left
' Original code by Andy Lansby
' https://zxspectrumcoding.wordpress.com/
' yPos is first, as it save a LD instruction when putting xPos and yPos into DE
ASM

JP START ; Put this in as it's like this on the Wiki ASM desciption - can it be avoided?
X_PositionBits: defb 128,64,32,16,8,4,2,1
; Might there be a quicker way to do the above, so it's not needed every time the program is run? or does it not work like this and is created once at compile time?

START: ; plot d = x-axis, e = y-axis
; A contains the yPos, xPos is on stack.
POP HL ; Pops the return address into HL
POP DE ; xPos is on the stack, and it needs to be in D
LD E, A ; A has our first paramter (yPos), load it into E. D should be Xpos, E should be yPos
PUSH HL ; Puts the return address back onto stack ...
; 166 T states per pixel
XOR A ; reset A to 0 and flags to default
LD A,E ; load Y plot point
RRA ; rotate Right --- divide in half
SCF ; turn on Carry flag-
RRA ; rotate right with the carry flag
OR A ; set flag S on - C flag off
RRA ; rotate Right --- divide in half

LD L,A ; temp store in L
XOR E ; XOR the Y value
AND %11111000 ; mask out bottom 3 bits
XOR E ; XOR the Y value

LD H,A ; store High byte
LD A,D ; load X plot point
XOR L ; XOR the temp value
AND %00000111 ; mask out unwanted bits
XOR D ; XOR the X value
RRCA ; divide by 2
RRCA ; divide by 4
RRCA ; divide by 8

LD L,A ; store Low byte
; now we have the full address
; now use LUT to find which bit to set
LD A,D ; load X plot point

LD DE,X_PositionBits ; load LUT address into DE
ADD A,E ; Add A to E to get offset into table
LD E,A ; E now points to the LUT entry
LD A,(DE) ; load answer into A

; output to screen
OR (HL) ; or with contents of address HL
LD (HL),A ; load address HL with Answer from A

HOF.zxbas - Hall of fame procedures
main.zxbas - a demo

Attached is a little "library" for a Hall of Fame / High Score table.

To use it - you need to create two Arrays (at least 2 ...)

Array 1 = UInteger, for scores
Array 2 = String, for names

Probably best to keep to 10 entries, but could be more.  You can have more than 1 HOF, so could have Array2, Arry3 etc etc for say Easy Score, Medium Scores, Hard Scores.  As it passes the Arrays by reference, no other variables are needed.

Completely and utterly free to use, adapt, change, republish how ever you want.

Arraybase is 0

SUB HOF_IntialiseHOF(BYREF HOF_Scores() AS UINTEGER, BYREF HOF_Names() AS STRING, HOF_IntialTopScore as UINTEGER,HOF_InitialName AS STRING)
Use this to initialise the two HOF arrays - with a "highest score, working down to a low score and gives each entry "InitialName".

FUNCTION HOF_HighScore_CheckEntry (HOF_Scores() AS UINTEGER, NewHighScore as UINTEGER) AS BYTE
Returns 1 if the High Score can g into the Arrays.

SUB HOF_HighScore_NewEntry (BYREF HOF_Scores() AS UINTEGER, BYREF HOF_Names() AS STRING, NewHighScore as UINTEGER, NewHighScoreName AS STRING)
Puts the new entries (name & score) into the HOF array.

SUB HOF_Print(BYREF HOF_Scores() AS UINTEGER, BYREF HOF_Names() AS STRING, YPOS as INTEGER, XPOS as INTEGER)
A simple print location, witch prints the Score and Names.  Will carry on printing if you have many entries ...

SUB HOF_PrintSpecial(BYREF HOF_Scores() AS UINTEGER, BYREF HOF_Names() AS STRING)
A "pretty High Score screen", that prints the top 10 scores.

Can probably be improved and made much more efficient.  There are porbably bugs as well (for example not sure what would happen if you had 100 entries with a first high score of 10 ... i think it's probably overflow to 655555 etc.  It includes string.bas and input.bas - not sure if the library needs both of those.

Use Project/Configure Project to configure.

Example Compiler Parameters

-O 0 -S 32768 -H 4768  -f tap -B -a

(The bold was auto generated, underscore are the options added "-f tap" to create a tap file, "-B -a" required to Generate the basic file and auto start.

Example Launch External Emulator

C:\zx\projects\DOSTesting\ZXStartFuse.bat

This has to be a batch file, rather than direct to the emulator, %1 and %2 are passed into the batch file for ZXBasicStudio - %1 is the path, and %2 the filename excluding the extension.

ZXStartFuse.bat created in the OS, and renamed to .bat, as it was txt file.

Code:
ECHO OFF
"C:\Program Files (x86)\Fuse\fuse.exe" -m plus3 --auto-load %1%2.tap


This would open a plus3 spectrum in fuse and run the tap file.

Also is it possible to include binary files in the assembler e.g.

BINARY 'test.bin'

I need to round or at least truncate a Float variable to 2 decimal places.
Do you know how this could be accomplished since there's no ROUND function?

Thank you very much,
