Third, the variant type is very resource-intensive, and considerable time is needed for the hidden conversion. Second, it allows you to control variables that can greatly facilitate the search for errors. First, it increases the readability of the text. For longer macros or those that will work in large documents, it is strongly recommended that you declare variables. If you write a macro from a pair of lines to work with small documents, you don't need to declare variables, as the variable will automatically be declared as the variant type. Strictly speaking, it is not necessary to declare variables in LibreOffice Basic (except for arrays).
Whether it makes sense to do so is up to you. Note: In examples that contain square brackets, if you remove the brackets, macros will show a window with an error. As you can see, you can use localized variable names. Here are some examples of correct variable names: MyNumber=5 Other punctuation or characters from non-Latin alphabets can cause a syntax error or a BASIC runtime error if names are not put within square brackets. They should start with either upper- or lower-case letters of the Latin alphabet, and they can include underscores ("_") and numerals. Variable names cannot contain more than 255 characters.
