Sweet! ;DNow I just need to learn Grammer

I worked on Grammer a little bit yesterday and at some points I  had precisely 0 bytes of coding space. However, I removed two undocumented experimental routines for sending/receiving bytes over the I/O port and now there are 69 bytes of coding space available!

As to the updates, I may have broken some things because I made a few more complicated modifications. I am pretty sure that I checked everything that could be affected, but I may have missed something.

• Else is finally added as a command. In a very basic way, Else works like you would expect:
  
  Code: [Select]
  If A=B
Then
<<do stuff>>
Else
<<do stuff>>
End

• Else has some complicated things that it can do. The way I implemented Else, it can stand alone as its own command. If you do this, it will seek an appropriate End token. For example:
  
  Code: [Select]
  While A>3
A-1→A
If A=5
Else        ;This will skip over everything until it finds the correct End
If A=4
Then
<<do stuff>>
End         ;not the correct End!
End         ;The correct End!
If you don't uderstand that, don't worry. As well, you can do something like this:
  
  Code: [Select]
  While A
A-1→A
Text(0,A,"O
Else
DispGraph
End
That is actually a neat trick to help you understand how Else works, but it isn't optimised That basically does this:
  
  Code: [Select]
  While A
A-1→A
Text(0,A,"O
End
DispGraph
Personally, I would just stick with the first use. The other methods will just complicate your code and probably cause confusion when parts of code don't work.
  
• Typewriter Text has been fixed! Now you don't need a DispGraph after using /Text( to see the last character.
• The degree token now acts as a command on its own, too. This can be used to temporarily change the draw buffer for the Text( command. Any command that has an optional buffer argument will revert the draw buffer back to normal. So for example, if Z points to the back buffer:

oZ           ;o is supposed to be the degree token
Text(0,0,"HI!
Text(6,0,"This is on another buffer.
Pxl-On(3,3
Text(0,0,"HI!     ;This is now drawn on the main buffer since the Pxl-On( command resets the temporary draw buffer
It also happens that this works for the particle commands as well, so now you can draw particles on back buffers without using complicated techniques.

 °Z is meant to work with RunPart Actually, AddPart does not require a buffer. If you want, you can use AddPart() with one buffer, then switch the buffer for RunPart and the particles would still be in the correct location on the new buffer.

Also, I think there were 18 bytes when I updated it, but I found extra code to delete

I also have never learned Grammar but probably should..   

Do you still plan a TI-84+CSE release, by the way?

Good news, everyone!

Two days ago, somebody who I will name only as Mx. Burch until I have permission otherwise, emailed me with a modified source for a newer version of Grammer than what I had. I had lost mnths of sourcecode for those who were not aware, and that basically killed the project.

They altered some code,  and I have not extensively tested the code, but hopefully there are no new bugs. Please be advised that this is an experimental version. If I work on this more, some of the additions will almost certainly change.

What was added? The >DMS token (in the Angle menu) is renamed "module" and tells the parser to search for a command in an experimental module. The availabe functions are TEXT( and DISP (with a space after it). These do precisely what the tokenized versions do (Text( and Disp, respectively). The appver Grampkg must be in RAM for now.

What was removed? The jump table is currently removed, so assembly programs using Grammer routines will likely crash. The 32-bit multiplication routine which is entirely unused in the app was removed, apparently the font was compressed, and I scrapped the custom VAT searching routine and I'm now just using the OS routines.

This leaves 927 bytes free! I plan to remove the menu and input commands to an external module since those aren't speed-critical.

From the looks of it, I think they disassembled the app and used older source code as a reference to piece it all together.

After only 7 years, a real  menu!:
