HELP - I AM STUCK! - TI EXtended BASIC

Since we're advertising our wares, here is Lee's running man demo in compiled BASIC. No changes required, just saved and compiled. Not as fast as the forth demo, but there are ways to get more speed... RUNNING.GIF.47e5b5d213d22d7ebfb8901fbb2b4568.GIF

Maybe wait for vsync? ?

I will try that tomorrow and see what happens. Probably there is a magic speed that just looks best and is more like jogging speed.

I just had to see how this would work at speed.

Very nice animation work by @Oddeman

I suspect the difference here is that you might be converting the text strings to integers for the patterns every time you run CALL CHAR() . (?)

When I tried it that way in Forth it was slower than your demo, because my CALL CHAR is also in Forth.

I pulled a stunt and borrowed the guts from my CALLCHAR and made it compile the strings as integers into CPU RAM as a contiguous integer array.

Of course then it goes into VDP RAM really fast with VMBW which I call VWRITE. Having access to the guts of the compiler is Forth's interesting feature.

You pay for it with a much longer learning curve.

I have to say that if your compiler existed in 1983 I would have probably never learned another programming language. Very very cool.

Yep, CALL CHAR is not the quickest way to do this, nor is it the most compact. The fastest and most compact would be to use XB256 which lets you save an area of VDP ram as a compressed data string. You can take a picture of the character definitions from 32 to 96, and put it in one (or more) strings. This uses RLE compression and the first couple of bytes has the address in VDP. The subroutine CALL LINK("CWRITE",...) decompresses the string and moves it into VDP ram in the same place from which it was saved. Very fast and very compact. I would guess the definitions would take less than 1K of memory.

I would estimate that this technique would let the program run in XB at the same speed as the compiled demo, and if compiled it would be like your forth demo. A big downside is that the process is cumbersome and changes are difficult to make.

Using the strings for character definitions in XB consumes 2 bytes for every actual character byte, so we could cut that in half by loading a block of character definitions. I do not know of an easy XB way to do this except to use an Assembly Language Code (ALC) subroutine. We would not need the repeated character set, so the block of character graphics would consume 4.5 KiB of RAM—still quite a bit. I do not expect you, @oddemann, to learn ALC, but, just for grins, I will write one you can load and call from XB.

Here is an ALC version to load from DSK1: RUNMAN.obj

Here is a simple XB program to run it:

100 CALL INIT
110 CALL LOAD("DSK1.RUNMAN.obj")
120 CALL CLEAR
129 ! CALL LINK("RUNMAN",row,col,delay)
130 CALL LINK("RUNMAN",3,1,10)
140 END

The delay (0 – 99) above is 10 times through the delay loop, which decrements a register 500 – 0, testing for 0 each time. The delay loop is run for each image change. It takes XB a god-awful long time to load the 4884-byte routine! If you change the delay to 0, you will see the running with no delay. Right now, you cannot interrupt the routine. I can change that or add another variable to limit the number of cycles through the images so you could set up several CALL LINK("RUNMAN",row,col,delay,cycles) statements for different speeds in the same program. Anyway—I had fun.

The ALC routine is in the spoiler:

My conclusion: Seeing all the different ways this can be solved!

BASIC and Ex BASIC is a good way into programming! But it is limited and slow! It makes one think that the tiny TI is slow! And all the other examples tells a different story.

The tiny TI is not slow, you just have to use its power in the right way. There are examples from down right stupid slow to insanely fast. So the power is there, to do stuff and also make great stuff.

If I am correct, the problem is memory! BUT, if one can keep feeding the TI with new data, then it is solved. If one can keep the 16k as "working memory" and when a program is bigger, then there is a way to put the data on hold on the "outside" until it is needed and then feed the TI. Then the sky is the limit for what one could do with the TI.

So the magic tool is from MY point of view... A program that can take BASIC or Ex BASIC (or any other) listing and translate it into something much more TI friendly for speed and what not, but also a good way to keep feeding the program with more data, WAY past 16k. Looking at all the stuff that is surrounding the TI, this tool is here (looking in the forum), but it is many different individual tools. Or maybe ANY lango of programming into the TI's preferred way of "talking". Then all the power is there. (Dream - A program that can translate ANY lango into TI's preferred way (fastest) of understanding. It would be a HUGE undertaking, and I know it will not happen. But I can dream and in my dreams it exists hehehe)

I learned a lot from the different ways to solve it and I understand that BASIC or Ex BASIC is really... REALLY limited! Then looking at the cool games made in BASIC or Ex BASIC, it makes it even more impressive. Also, I guess if one would use this "tight" way of programming in the modern PC, it would unleash so much more power there too. One can only guess to how much power is lost to sloppy programming!

Furthermore... How much more power is there to press out of the tiny OLD TI? And looking at what is being done today, I think there is more! But, there is also a limit to how MUCH more.

Looking at all the stuff being done for the TI, all this into one tool - "To rule them all!", and with the hardware updates... 2021 TI-99/4A with all this mixed together - It would take advantage of all possibilities and make it shine!

***

It is cool to see that the Old tiny TI still has the power to spark imaginations, some 40 years later!
(Myself, I am looking forward to the F18A Mark II)

***

PS! @Lee Stewart, I tested your new way of doing it... All I can say... so nice! ? And looking at the listing... wow, that is a lot more reading and learning :p hehehehe

"It takes XB a god-awful long time to load the 4884-byte routine!"

I hate to turn every post into an advertisement for XB 2.8 G.E.M., but if you tried it out, you would see this is no longer a problem.

I am well aware that there are better (read, “faster”) ways to load object code than standard XB. I was quite simply floored by how abysmally slow XB’s loader actually is. Your incorporation, Harry, of the MiniMemory module’s object-code loader into XB 2.8 G.E.M. is a phenomenal enhancement, I must say.

I could not resist playing with this just a bit more.

Edit: Doh!. It's smoother when you use all the frames. (9 MOD versus 8 MOD)

I did some work converting the character patterns into compressed data statements to run with XB256. Earlier, I was a little over optimistic about the amount of compression that would happen, thinking the data would be about 1K long. As it turned out, after being compressed, the data statements use 1760 bytes of memory. (Compared to 9000 bytes in the original program). As I speculated, when using compressed data statements and CWRITE the speed while running in XB is about the same as the compiled version of the original program. Of course, this program can be compiled and the results are in the short video below.

In the folder are:

RUNNING-X compiled version of original program

RUNNING256 Requires XB256. XB version using compressed data and CWRITE to write the definitions to VDP.

RUNNING2-X compiled version of RUNNING256 (shown in video below)
