Hi my Friends,

I’ve been playing a little bit, and finally I could assembler this Code

10 ORG 16384

20 LD A,1

30 XOR A

40 END

ASSEMBLE

¿Any help for commands, in particular for loading/saving binary and source code?

Hi,

you can use the built in assembler of the emulator to put the code straight to memory.
That is good for testing and fast development.
For Newbas from what i remember you have to save the object file to disk or tape and then make a small
basic loader to put the bytes to memory.
Something like this ( i am doing this from memory so some mistakes my exist):
tape must be at the start of the file, usually the loader precedes the object file, filename is optional
10 Openin#1,1,”Filename.o”
15 k=16384:n=<your filesize>
20 for i=1 to n
30 get#1,a:poke k,a:k=k+1
40 next i
45 close#1
50 call 16384: Rem if you want to execute the code
100 end

for disk change line 10 to
10 openin#9,9,”filename.o”
filename is required

Thanks CDesp,

Very helpful. After assemblig I get a message showing tape is ready.

First I’ll have to struggle to check how to save,  I suppose then there is not a guide / list of commands for Newbas assembler.

Hello CDesp,

Sorry, but that’s an IA alucination.

After playing around:

LOAD FILENAME ; do not use quotes for loading source file

SAVE FILENAME ; do not use quotes for saving source file

ASSEMBLE FILENAME ; do not use quotes for saving compiled source code. After message Tape Ready, press enter for saving.

Thanks anyway

You are right that was all wrong.

Well here are the keywords i found from the binary

AFTER ASSEMBLE IS FINISHED PRESSING A KEY SAVES THE BINARY FILE TO UNKNOWNx.BIN ON THE TAPE DIRECTORY
ASSEMBLE COMPILES THE SOURCE
LOAD LOADS THE SOURCE FILE (SELECT THE FILE TO LOAD FIRST)
SAVE SAVES THE SOURCE TO UNKNOWNx.BAS
DEL <LINENO> DELETES A LINE
LIST
NEW CLEARS THE CURRENT PROGRAM
OLD REINSTATES THE OLD PROGRAM USE AFTER NEW
PLIST LISTS TO THE PRINTER ANSWER Y ON START (ON THE EMULATOR THAT IS PRINTERNEW.PRN)
REN <NUMBER> IT RENUMBERS ALL COMMANDS FROM NUMBER (10 IS THE SPACING)
MEMORY SHOWS FREE MEMORY
DLOAD NOT WORKING ON TAPE (DISK)
DSAVE NOT WORKING ON TAPE (DISK)
RUN LOADS FROM TAPE BUT WHAT
MAN CRASHES

Many thanks again CDesp four your help 😉

Also I observe that ASSEMBLE is only into file. Using NewBrainemu I checked nothing is poked into memory.

RUN also is a mistery to me, after executing, the listing is lost forever.

Hi CDesp,

Finally understood RUN command.

You have first tonplace the tape with output compiled code with ASSEMBLE in the emulator

After executing RUN a message shows Tape in Ready. Press Enter, and then loads into memory and execute the code 🙂
