1-If I create a function with the 'function' keyword as shown in screenshot Ek-1, the system compiles it, but when I write it completely in uppercase, I get an error like in Ek-1. Could this be due to my PC settings? Or is there a Java-related bug here

2- I cannot enter the procedures and functions I have created; it gives an error as shown in the attachment. EK2
Please, I request your assistance regarding these matters
