Grammer Q&A

[Xeda112358]

The app version has more features and lets you run the programs from archive and whatnot. So it is more crash resistant

[BlakPilar]

Ahh, okay. I shall give it a try soon, then.

I just took a look through the documentation and how do I get the user input of a string or a number?

[Xeda112358]

With the latest version, you would use Input →A to let the user input a string. You can use expr( to convert the string to a value (by executing the string as code).
So for example:

Code: Select All | Copy To Clipboard

1 2 3 4

Text(0,0,"Name DispGraph Input→A

or:

Code: Select All | Copy To Clipboard

1 2 3 4

Text(0,0,"GUESS DispGraph expr(Input →A

The input routine isn't great, but it is rather adequate

can you write down all the prefixes? so far, all I know is that e is program, and v is appvar.

[C0deH4cker]

@Xeda: with those commands, it would be possible to create an interactive grammar interpreter (although impractical), right?

[Xeda112358]

@Yeong: I should remember to include the chart in the readme... For now:

Code: Select All | Copy To Clipboard

1 2 3 4 5 6 7 8 9

D=Str E=Program F=Protected Program G=Picture H=GDB U=Appvar V=Temp Program W=Group           ;be careful with this one!

@C0deH4cker: I've no clue what that means, but Grammer is Turing Complete (I believe) and so can emulate other Turing machines, so you can create a new interpreter from Grammer

[Yeong]

wait....I could do group? and Pic? O.o

I feel like Full'd (no pun intended)

[Xeda112358]

No, you should not write to a group Only read from it unless you know exactly what you are doing! Creating a group could cause some serious issues...

[Yeong]

yet another question:
Is there a way to "jump" to another Grammer program?
(Except for the not putting "stop" in end of the program and let it "naturally" run the program right below it. )

[Xeda112358]

Yes, actually. All you need is a pointer to the program and then you use either Goto or prgm like you would a label. So to jump to prgmSubEnd:

Code: Select All | Copy To Clipboard

1 2	Goto Get("ESubEnd

This is actually the main reason for why the program header starts with a decimal as that line will be ignored when calling the program.

[Yeong]

I actually found the other way to deal with it... (Check Grammer2 APP thread)
but there was an easy way

[Yeong]

Feature request: is there a way to "include" the TI-BASIC command? I know that Grammer 1 let me do so, but I don't know about the Grammer 2.

[Xeda112358]

Hmm, I am not sure what you mean... I think you mean allow BASIC and Grammer to be mixed? I could try to whip something up for you You will need to have a program in RAM to do it, but yes.

Also, I will make a Feature Request topic as you requested on IRC

[Yeong]

I think you mean allow BASIC and Grammer to be mixed?

That's exactly what I meant.
