Why do I get the message "Extra ignored!" in my MVI56-BAS module?

That means that somewhere in your program you are assigning to a string a value larger than the defined limit using the string statement. In a program that uses strings you need to place at the start of the program the following statement:


where a = total number of bytes for the all strings and b = maximum number of bytes for each string. When you exceed the value of b on any given string you will get the "extra ignored!" error message. To solve this problem you can raise the value of b or reduce the length of the strings that you are using on your program.
