Random is either read or write. Binary mode allows you to read a file determining the number of bytes read, not the number of characters.
For files opened in Binary mode, all of the Random rules apply, except:

·      The Len clause in the Open statement has no effect. Put writes all variables to disk contiguously; that is, with no padding between records.
·      For any array other than an array in a user-defined type, Put writes only the data. No descriptor is written.
·      Put writes variable-length strings that are not elements of user-defined types without the 2-byte length descriptor. The number of bytes written equals the number of characters in the string. For example, the following statements write 10 bytes to file number 1:

VarString$ = String$(10," ")
Put #1,,VarString$
