according to the manual:

string s[30];
...
str_for_num(s,sqrt(2));

I can set a var value into the string

now using:

STRING* se[30];
...
var kk=40;
str_for_num(se,kk);


just returns:

"Invalid arguments in Lite-c: STRING"

(definintion in afuncs.h)
EXT STRING* F(str_for_num)(STRING*,var);


The manual is just explaining the old C-Script!

Can anyone explain me how to store a var value into a string in Lite-C ?
