Are you in Algebraic or RPN???

ILAP error is just becouse this function works respect to the default
independent variable X... in your case the calc is assuming the
function as a constant...

SQ means to say Squared... SQ = 2 ^

I dont understand very good the third question... could you please
make it again...

Hope it helps...

If you get SQ(anything) and press EVAL again then you will get it in
terms of anything^2.

I will try to look into the third question tomorrow.

Hi articavenger.
As far as your 3rd question goes, even though it's not fully clear to
me, here follows what the 49G+ Advanced User's Reference Manual says
about the PR1 command:

PR1
Type: Command
Description: Print Level 1 Command: Prints an object in multiline
printer format.
All objects except strings are printed with their
identifying delimiters.
Strings are printed without the leading and trailing "
delimiters.
Multiline printer format is similar to multiline display
format,
with the following exceptions:
- Strings and names that are more than 24 characters long are
continued
on the next printer line.
- The real and imaginary parts of complex numbers are printed on
separate
lines if they don't fit on the same line.
- Grobs are printed graphically.
- Arrays are printed with a numbered heading for each row and with a
column
number before each element.
For example, the 2 × 3 array
1 2 3
4 5 6
would be printed as follows:
Array (2 3)
Row 1
1] 1
2] 2
3] 3
Row 2
1] 4
2] 5
3] 6
Access: [RIGHT SHIFT][CAT][PR1]
Flags: I/O Device (-33), Printing Device (-34), Double-spaced Printing
(-37),
Linefeed (-38). If flag -34 is set, flag -33 must be clear.
Input/Output:
Lev.1/Arg.1 Lev.1/Item 1
object object

Hope this helps.
Best regards.

Thanks everybody,though I didn't get why ILAP doesn't work properly. I
need that function for my Control System exam. I'll just avoid using
it and stick with the tables. Anyway, I'm just starting to use and
program calculator,and I'm also new to RPN so I might have some more
questions for dummies.

If 'S' is your variable name then do 'S' STOVX 1st
If 'MyVar' is the LAPlace, Integrate, REVX variable
then do 'Test' STOVX and try again
The Header shows typically
RAD XYZ DEC R= 'X'
or
DEG R<< HEX C~ 'Test'

RAD DEG is Angle unit
XYZ R<< is Coord type
DEC HEX is binary base
R C is Real Complex
= ~ is Exact (integers) vs. Approx
'X' 'Text' is VX or Variable used in eXecution name
maybe you guess the rest...
