Я открываю вайл для двоичного чтения
Дальше мне нужно его считывать по байтам в массив и иметь возможность по нему перемещаться.

Пожалуйста подскажите какие функции для этого можно использовать.

Open Statement

Enables input/output (I/O) to a file.

Syntax

Open pathname For mode [Access access] [lock] As [#]filenumber [Len=reclength]

The Open statement syntax has these parts:

Part Description
pathname
Required. String expression that specifies a file name — may include directory or folder, and drive.

mode
Required. Keyword specifying the file mode: Append, Binary, Input, Output, or Random. If unspecified, the file is opened for Random access.

access
Optional. Keyword specifying the operations permitted on the open file: Read, Write, or Read Write.

lock Optional.
Keyword specifying the operations restricted on the open file by other processes: Shared, Lock Read, Lock Write, and Lock Read Write.

filenumber
Required. A valid file number in the range 1 to 511, inclusive. Use the FreeFile function to obtain the next available file number.

reclength
Optional. Number less than or equal to 32,767 (bytes). For files opened for random access, this value is the record length. For sequential files, this value is the number of characters buffered.

Remarks

You must open a file before any I/O operation can be performed on it. Open allocates a buffer for I/O to the file and determines the mode of access to use with the buffer.

If the file specified by pathname doesn't exist, it is created when a file is opened for Append, Binary, Output, or Random modes.

If the file is already opened by another process and the specified type of access is not allowed, the Open operation fails and an error occurs.

The Len clause is ignored if mode is Binary.

Important In Binary, Input, and Random modes, you can open a file using a different file number without first closing the file. In Append and Output modes, you must close a file before opening it with a different file number.
