====== WRITE# ======

The ''WRITE#'' command is used for saving the contents of a variable to a file. The file must be opened first using [[OPEN]].

  WRITE #<logical_file_no>, <expression> [, <exrpession>, ... ]

The ''WRITE#'' command is similar to [[PRINT_hash]] in that both commands output sequential data to a file. However, while ''PRINT#'' outputs PETSCII-encoded (textual) data, ''WRITE#'' outputs binary data. To illustrate:

  * ''PRINT#'' is used to store data that can be restored using [[INPUT_hash]]
  * ''WRITE#'' is used to store data that can be restored using [[READ]]

<adm warning>
The ''WRITE#'' command accepts any number of arguments of any type. As data will be output in a raw binary form, without separators, it is very important to make sure that each datum is in the exact same type and order that will be used when reading.

<adm warning>
File I/O commands are not implemented for the Commodore PET.
