# WriteFile (filename$)

# Parameters

filename$ = any valid path and filename. The returned value is the filehandle which is an integer value.

# Description

This command opens the designated filename and prepares it to be written to. Use this to write your own configuration file, save game data, etc. also useful for saving custom types to files. The filehandle that is returned is an integer value that the operating system uses to identify which file is to be written to and must be passed to the functions such as WriteInt(). If the file could not be opened then the filehandle is Zero.

# Example

; Reading and writing custom types to files using ReadFile, WriteFile and CloseFile
; Initialise some variables for the example

BestScore = 11657
BestLevel = 34
; Open a file to write to
fileout = WriteFile("mydata.dat")
; Write the information to the file
WriteString( fileout, BestName )
WriteInt( fileout, BestScore )
WriteByte( fileout, BestLevel )
; Close the file
CloseFile( fileout )
; Open the file to Read
filein = ReadFile("mydata.dat")
; Lets read the Greatest score from the file
Greatest.HighScore = New HighScore
GreatestName$ = ReadString$( filein )
GreatestScore = ReadInt( filein )
GreatestLevel = ReadByte( filein )
; Close the file once reading is finished
CloseFile( filein )
