Be Firm
Code
#be firm
tellme("This line is okay.");
tellmee("This line is an error.");
Console
Error: “tellmee” is undefined on line 4.
Explanation
The #be directive can be followed by either firm or gentle. Here, the programmer uses firm to inform the processor that they want error messages to be straightforward and concise.
#be firm
Thus, when tellme is misspelled as tellmee on line 4, the error is pointed out in the console, with no additional information.
