Undocumented Tricks in Basic

yes, it is a shame. if i ever convert DraognOS to asm i might make it a complete os for the calc (to replace the ti-os). i wouldnt be skimpy on the things basic programmers could do. i would shoot for the only differece being the speed of execution between asm and the basic Smile

tell me when you get done with it... i cant get my asm to hexdecimal thing working (or ever did) so that os would be nice

YAY! Someone cares what I say! I'm not useless! YAY! Very Happy

I made an asm 'compiler' in basic, but I got bored after adding _clrLCDFull and ret.

It would just ask for input, change the input into hex codes and add it to a string, which you could paste into a new program and then execute it as asm.

i was thinking of making one in VB but then i would have to learn how to "program" again... it sould be rather simple due to VB being almost idoit proof

True, true, now let's see if we can find more 'undocumented tricks', eh?

i found one, know how u can do the Text(-1,0,90," ") do get rid of the RI? well, on the homescreen just do Output(1,16," ") and it does the same... (actually is the exact same effect, it is only useful if u dont use the last space on the first line Neutral

Try something like this with variables, strings, ect:
15
Output(Ans,1,"Blah
Output(Ans,2,"Blah
Output(Ans,3,"Blah
Output(Ans,4,"Blah

Something like that. It will save space if there are enough of the command after it.

no, it's not prohibited. sorry, that got clarified. having your own OS is fine, except you can't tell people how to modify it for loading or have it pre-modified.

Oh, I see. It would still be a lot of work to replace the OS, and you would have to provide support for all ASM commands, so basically the OS would be the same, if not worse. You could, however, make it more graphical, but you could do that without editing the OS.

no, not that you'd have to provide support for asm commands, but once it is compiled there are a few bytes that must be changed so that the calc verifies it as a valid OS.

Thats true, the asm is compiled into hex in TASM, the calc doesnt do it.

Once i typed in "ABCD->X, and "ABCD" was somehow stored to list X. Is there any way this could be used to have extra strings in a program?

yes
that is the formula
like
do this:
{1,2,3,4,5,6,7,8,9->L1
"L1+2->L2

if you look at L2, it will be {3,4,5,6,7,8,9,10,11}

Writing a stupid program, I noticed ClrDraw clearing some variables... which ones does it clear and why?
