----------> All Credit To Marcel (mkanter) for discovering these <------------

apparently there are some hidden commands on the classpad, these are the ones that have been found so far:

cmds:
Receive param1
Send param1
CheckNaturalNum param1

fcts:
element(list,nr) or element(matrix,row,col)
completeSqr(param1)

I've asked casio about them (and asked if there are more), I'll let everone know what they say.

[mkanter]

there are more, but these (i think) are internal commands.

Receive and Send may are there for "backward" compatibiliblilttily (i'm not doing drugs!!!) with older programs, or the Send38k and SendVar38k do there stuff only with the Send command.
however, Receive works without opening the ComPort (no error doing e.g. "Receive g")

element() gives an specific element back:
#y[1,1] is not possible but element(#y,1,1) (if #y is a matix)

CheckNaturalNum and completesqr are doing something, but there is no output (or i have'nt found it)

btw there is apply() (used in main), conicsForm (not testet)
and MeanBox (does not work (with StatGraph (it's located with ModBox and MedBox)) - i think it's for later use (higher OS ver))

Out of topic (good advice to anyone who tries to do what i do):
Don't do it (that's wrong: don't try it - then it's not too late).
It does not bring you to something,...
and you become lonely, very very lonely.
If you have an girlfriend don't say a word about this (if you didn't follow my advice).
If you do you'll see why...
In my case it's too late...

conicsForm has tis syntax:

concisForm(expr1,num1) where num1 can have these values: -1, 0, 1.

Function returns list of values (8 items); the last one is expr. others are numbers.

num1:

for -1 returns only expression
for 0 returns list of values, last item is expression in "fit form" (I hope that you understand because my english isn't so good). Same result you get when you apply "Fit into Conics Form" in Conics application.

for 1 returns list of values with unchanged expression.

As I've wrote, function returns list of eight items. I think that the first 7 items are coeficients of expression.

For example:
x^2 + y^2 - 4x +9y - 5 = 0

conicsForm(x^2+y^2-4x+9y-5=0,1) returns {1,0,1,-4,9,-5,1,x^2+y^2-4x+9y-5=0}

items correspond with coeficients from expression>

1 => a x^2
0 => b xy
1 => c y^2
-4 => d x
9 => e y
-5 => f
1 => ???

I don't know what the last number means.

I've been able to find out that CheckNaturalNum does nothing, its a removed command.
