Glad you like it! The use of line numbers is an (un)fortunate symptom of using the BASIC entry mechanism to enter code. The positive side of having to use line numbers due to the BASIC environment is that it doesn't require a separate editor program to run and manage program development, along with having the ability to mix BASIC and Assembly.

The way to reference a Kernal subroutine by label in any label oriented assembler is to define it's location in the listing, usually at the top, for example; chrout = $FFD2. Then your listing can use the label as in; JSR chrout. The reason this is not included automatically in most assemblers is because not all 65xx code is intended for the C-64 and the location will not apply to those other computers.

I've been using the PAL assembler since the 90's (and still do today) so it was fun to see it featured on a KZbin video! The line-number thing is both a blessing and a curse. Moving chunks of code is a hassle. I've grown used to its 8-character label size limit. I love how PAL adjusts itself to where you've set the top of BASIC to when you first install it. Source is easy to tweak. You can even write it without the assembler present! Something I noticed you did not do when first running PAL is a NEW command. That leaves you with less memory than should be there. Worse yet - check this out - it causes your source file to be bloated with this hidden garbage too! Here's proof: LOAD and RUN the PAL assembler, write a one-line program, and save it to disk. It's 27 blocks! I never realized this flaw existed because I always NEW. What another user pointed out (and yourself mentioned) is the missing RTS around 53:50 in the video. I bet the program DID clear the screen, but since you're using an emulator, the next byte was likely zero, causing a BRK which cleared the screen (again) and dumped you into BASIC, just like STOP/RESTORE would. On a regular machine, it would more likely be an "unfortunate" outcome. I had to jump the video back to 49:00 because I was sure you hit RETURN on "100 waitloop = *" which you did. The thing is, immediately after it, you also called the next line of code line 100 too, and yeah. LOL it happens, and it has happened to me too. Anyways, sorry for rambling on like this. This video got me excited and appreciative of the assembler I've become so used to using. Do you always use ".OPT P,OO" when you code? I usually just .OPT OO and any errors pop out, because the code created isn't shown. Assembles faster too. But for the case of this video, it made perfect sense to show the code it makes.

Many years later when I moved to PC, I was surprised that self modifying code isnt common practice on PC. Is it possible to write self modifying code using assembler?
@VintageVolts Жыл бұрын
Assembler is more of an enhancement to the mnemonics used in a ML Monitor. If you don't rely too much on the actual memory addresses the Assembler assigns to labels in the source code, you can probably get away easily with self-modifying code, as long as it doesn't mess with the converted label addresses. Once the code is assembled, there is no need to track labels by name, just their actual values. Although, it is conceivable that you could create a lookup table of those label's actual values of some sort, perhaps to change code related branching, specially crafted to allow the Assembler to insert memory addresses for labels into a memory space outside of the program execution space. Then use some sort of trick to retrieve the original label addresses, perhaps push them to the stack, to allow you to replace the original label values in the main code. It would most likely require some research before starting to write code to keep the concept under control.
@lupedarksnout Жыл бұрын
I use PAL on the C64. Self-modifying code is very possible on PAL. I've used it when the situation calls for it. Easy enough to set up. A line of source like "100 SM100 LDA #0" can later be altered semi-permanently while running with a STA SM100+1 wherever needed. You can label them however you want of course - this is just what I do. Remember also it's only this "default" value when you first assemble it, which can be more risky if you're altering opcodes instead of merely data.

I still shake my head seeing this. How awkward to use BASIC line numbers instead of memory addresses. But at least we were spared all that BASIC READ and DATA stuff. My first computer was a single board computer with a hexadecimal keyboard and the first thing I ever learned was how to write machine code programs. A rough start maybe, but what I learned from that served me well on every computer up until today. And I never took much more than a look at BASIC or any other interpreter. Compilers, yes, but interpreters are just a waste of some a computer's most precious resources. Especially on 8 bit processors where these resources are not abundant in the first place.
@VintageVolts Жыл бұрын
The point of using the BASIC line numbers in this case is because it leverages the intrinsic capabilities of the system. Why reinvent the wheel when making an assembler, which will need editing and save/load routines, etc., for a BASIC based system when the system already includes an interactive editor screen, save/load routines, etc.? That was one of the original intents of the PAL Assembler, which leaves the code responsible for actually doing the assembly smaller in size AND tucks it into a little bit of RAM at the top of BASIC RAM. The only caveat is to work within the confines of that editing environment, thus requiring line numbers. Outside of the fact that PAL Assembler allows for a mix of BASIC and Assembly in its source code, which helps those who are familiar with BASIC to bridge their knowledge gap to Assembler, BASIC itself is only needed for the SYS call at the start of the source code. Everything else is nothing more than structured code. As with any programming environment, there are syntax rules that are required to be followed for the source code. So what if you have to use line numbers? If that requirement is too cumbersome, the PAL disk comes with the POWER 64 toolkit, which includes a line autonumber command. Just run that and it will automatically create your line numbers for you as you type in your Assembly source. As far as using memory addresses instead of BASIC line numbers, assembly never uses a series of memory addresses. It uses a Program Counter reference. Addresses are dealt with by the assembler. If you're coding machine language on a screen requiring you to type and track memory locations, then you're most likely using a machine language monitor, not an assembler. It's only awkward if you haven't spent a lot of time using BASIC.
@CDP1861 Жыл бұрын
@@VintageVolts My old computer started out with 256 bytes RAM and no ROM at all. You could enter instructions with the hex keyboard sequentially and then run your program when you were done. The first expansion was indeed a tiny 256 byte ROM with a small monitor program that allowed you to enter bytes at any location, examine memory at any location and load or save programs to tape. Other expansiones followed, but pure machine code and real memory addresses remained the best way to write programs. Even assembly was not a step forward because of a design feature of the processor which did not allow you to fully forget about memory addresses and just use labels instead. Indeed, I'm still wrestling with that problem today. I still have that old computer and these days I of course use a cross assembler on a PC and test my code in an emulator. I can still transfer the finished program to the old computer when it's finished. My whole point is: Both assembly and machine code give you enough to learn already. Why also keep on wrestling with BASIC? These days you can deactivate it and enjoy the luxury of more free to use memory. Do your development on a PC and you have all that the old machine has to offer at your fingertips. BASIC is an awful development tool and also an awful replacement for an operating system. So why hang on to a crutch that you are going to have to get rid of anyway?
