I didn't understand then...
What do you want to store and show?

I solved the problem. I thought that a list of arguments, separated by commas, was auto-typized: if argument 1 is a string, <ARGV[0]> is treated as a string, if argument 2 is a number, <ARGV[1]> is treated as a number. So, if i passed as the second argument "12" and in the function i do SAY <ARGV[1]> it would show 0c instead of 12, because numbers are automatically parsed in hexadecimal.
Though, doing SAY <ARGV[1]> shows "12" and not "0c", so in this case argument is treated as a string and not as a number, i was wrong.
The problem lies in the LOCAL._TEXT=<ARGV[4]> in my function (5th argument is the text). If i assign the value of <ARGV[4]> to a local (tag, var, whatever), sphere automatically recognizes the type of the argument, and internally set the local to be a numeric variable, since i am passing "12". So, as numerical variables are parsed in hex, doing SAY <LOCAL._TEXT> will show "0c", both in the case i passed "12" (so it was like LOCAL._TEXT=12) and in the case i passed "0c" (like LOCAL._TEXT=0c).
On the contrary, SAY <ARGV[4]> shows "12" if the argument is "12" and "0c" if the argument is "0c". This because internally <ARGV[4]> is a string, so it have not been parsed in hex or in decimal.

To sum up, i was misled by the fact that:

Code:

[FUNCTION test]

SAY <ARGV[0]>

LOCAL._TEXT=<ARGV[0]>

SAY <LOCAL._TEXT>

.test 12 shows first 12, second 0c. The explaination is the one above.
It's like doing:

Code:

[FUNCTION test]

SAY <ARGS> //shows 12, because the argument is treated as a string and i print it out as i pass it

SAY <ARGN> //shows 0c, because the argument is treated as a number and sphere parses it in hexadecimal

I don't know if a number or a text will be passed to the function, so i cannot do SAY <EVAL <ARGN>> or SAY <HVAL <ARGN>>.

In my code i did:

Code:

LOCAL._TEXT=<ARGV[4]>

LOCAL._TEXT=<ASC <LOCAL._TEXT>>

And i got that problem, which i solved doing this:

Code:

LOCAL._TEXT=<ASC <ARGV[4]>>
