Put (File I/O)

The value passed to Open when the file was opened.

Is the position where Put must start in the file. If the file was opened For Random, the position is in records, else it is given in bytes. If omitted, writing starts at the present file pointer position. The position is 1-based: i.e. the first record or byte of a file is at position 1.
If position is omitted or zero (0), file writing will start from the current file position.

Is the buffer where data is written from. It can be a numeric variable, a string, an array or a user-defined type. The operation will try to transfer to disk the complete variable, unless amount is given.
When putting arrays, data should be followed by an empty pair of brackets: '()'. Put will write all of the data in the array. amount is not allowed.
When putting Strings, the number of bytes written is the same as the number of bytes in the string data. amount is not allowed.
Note: If you want to write values from a buffer, you should NOT pass a pointer to the buffer; instead you should pass the first variable in the buffer. (This can be done by dereferencing the pointer with Operator * (Value Of).) If you pass a pointer directly, then Put will put the memory from the pointer variable, not the memory it points to.

Makes Put write to file amount consecutive variables to the file - i.e. it writes ( amount * SizeOf(data) ) bytes of data, starting at data's location in memory, into the file. If amount is omitted it defaults to 1, meaning that Put just writes a single variable.
