Naming of VB variable names:

The naming rule of variable names is: within 255 characters, the first character is a letter, followed by a combination of letters, numbers and underscores, and the last character can also be a type descriptor. Usually, variable names with certain meanings are used, which helps to explain the function and simplify the debugging process. Reserved words cannot be used as variable names.

Put the type symbol at the end of the variable to explain the different types of the variable. Type description is as follows:

% stands for integer. Represents a long integer! Stands for single precision type, # stands for double precision type, @ stands for universal type, and $ stands for character type.
