Re: printing values from udf!!!
you can write in your udf the printf statement as you do in C programming. it will print whatever values you want.

Re: printing values from udf!!!
You can use the command:

Message ("Text %g \n", var_name);


- Text is a string.

- %g is the placeholder where the value of the variable var_name will be written. %g is for real values, if you want to write an integer (int) value, use %d.

- \n is the new line command.

For example, if you want to write two variables i (int) and s (real), viewing something like this in the console:

"The value of i is 9 and the value of s is 3.5."

you have to write the command:

Message("The value of i is %d and the value of s is %g\n",i,s);
