Grammer 2-The APP

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 All | Copy To Clipboard

1
2
3
4
5
6
7
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 All | Copy To Clipboard

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 All | Copy To Clipboard

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 Tongue

That basically does this:

Code: Select All | Copy To Clipboard

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:

Code: Select All | Copy To Clipboard

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.
