When I enter
(type (read "0.01"))
it returns SYM instead of REAL

How is this possible?

(On another computer, with the same configuration, it does returns REAL)

Thanks!

You typed the letter "O" instead of the numeral zero.

Are you typing this manually?  If so I agree that what Owen wrote is the most likely cause.   If this is part of a lisp routine that you load then the only reasonable possibility other than typing the letter O instead of the number 0 is that the two computers do not have exactly the same software and exactly the same add-ons and lisp routines.

Hi,

On the computer which return the SYM type, is the dot (.) set as decimal separator ?

Here:
Quote
Commande: (type (read "0.0011"))
REAL
Commande: (type (read "0,0011"))
SYM

Do you mean the Windows setting?
In Windows the dot (.) is set as decimal separator.

Two things worth looking into:
1.
Check what (type (read "1")) returns on both machines.
2.
Type "0.0011" in a text file on both machines and compare the files.

"1" returns INT on both
"0.0011" returns SYM and REAL (copied from the same textfile)

On the machine returning SYM is comma a decimal separator? Its a very common problem when dealing with multiple regions.
