Ok.. Here's a nutcracker...

In the time of Philemon BBS systems you could use a tool called 'makebin' to create a binary files from a basic listing (it had something to do to make the load process faster).

I remember that there are 2 several pokes (I thought it had something to with &h8001) to make the listing visible again.
Does anyone know the pokes you need to use to make a binary file visible again?

Didn't that depend on the specific listing? Try peeking it before you bsave it. I do remember the pokes (I used them too) but think it really was kinda listing specific. I think it indicated the length of the listing. If you poked just anything you'd get crap after the listing end, which you then had to delete.

&h8000 = 0
&H8001-2 i think would point to the free RAM for variables (the next to the last byte used by the BASIC program)

but not check it

I recently found all my original Philemon disks and TNI BBS backups (along with a lot of 'forum' messages from that time! ^_^).
I'll try to find some time to weed through them to find the documentation of MAKEBIN.

BTW, your memory about the purpose of MAKEBIN was correct. BIN files load a lot faster than BAS files, and since most BBS's ran on floppy in those days...

Your BASIC knowledge seems to be in rust!

I have newer heard of this MAKEBIN, but I can help you with these BASIC things.

The BASIC memory starts from &H8000 or actually from address: peek(&HF676)+peek(&hF677)*256-1

I anyway refer it here just &H8000 as that is a typical situation.

&H8000 (byte) must be 0 to be able to run the program.
&H8001 (word) points to the address of next BASIC line. (next equal address as this is)
&H8003 (word) here is linenumber
&H8005 Here is tokenized BASIC line that is zero terminated.

You can restore the address in &H8001 by searching the next BASIC line start. That can be done for example like this: (NOTE: Do not add line number, that will mess up the memory area, we try to restore)

A=PEEK(&HF676)+PEEK(&HF677)*256:AD=A+3:FORI=0TO1:I=0:AD=AD+1:IFPEEK(AD)=0THENAD=AD+1:A1=INT(AD/256)OKEA,AD-A1*256OKEA+1,A1ELSENEXT

I made a little binary for this purpose. You need to load the Basic program you want to save as a binary file and the run my binary. It adds a small piece of binary right after the Basic code and returns a BSAVE command with the necessary addresses to load and start the Basic program. All you need to adapt is the file name in that line and execute it.

The archive is complete with source code slightly modifed for tniASM.
