LEN

the LEN command (short for "length") is used to determine the length of a string, or the total number of characters in the string. This is a very useful command when you need to know the size of a string to perform manipulation or comparison operations.

You can check whether a string exceeds a certain maximum length or not. You can use LEN to create strings of a fixed length by adding spaces or other characters. You can combine LEN with other functions such as LEFT$, RIGHT$, and MID$ to extract and modify parts of a string. You can compare the length of two strings to make decisions in your program.

EXAMPLE

 x = LEN( "TEST" )
