Put Statement diagram

Put [#]fileNum, [recordNum|filePos], variable


fileNum: Any integer expression that defines the file that you want to write to.

recordNum, filePos: For relative files (random access files), the number of the record that you want to write.

For binary files (binary access), the position of the byte in the file where you want to start writing.

variable: Name of the variable that you want to write to the file.

Note for relative files: If the contents of this variable does not match the length of the record that is specified in the Len clause of the Open statement, the space between the end of the newly written record and the next record is padded with existing data from the file that you are writing to.

Note for binary files: The contents of the variables are written to the specified position, and the file pointer is inserted directly after the last byte. No space is left between the records.
