MakeFile

MakeFile Filename$, Size

Parameters:

Filename$ = The Filename of the file you wish to create
Size = The size in byte of the file

Returns: NONE

MakeFile will create a blank file. The file will contain only zeroed bytes.

This only really useful when you need random file access.

FACTS:

* Before you use MakeFile, always check if the filename (of the file your about to create) already exists previously. If you try and overwrite a file that already exists, PB will return a run time error.

Mini Tutorial:

This example will create a blank file on the C: Drive called "TestFile.txt" , it then displays the info about this file and then removes itself.

; Create a variable of the files Filenames
  Filename$="C:\TestFile.txt"

; Make the blank file, 100 bytes in size
  MakeFile Filename$,100

; display the info about the created file
  Print "File Name:"+Filename$
  Print "File Exist:"+Str$(FileExist(Filename$))
  Print "File Size:"+Str$(FileSize(Filename$))

; now delete this file, as it's no use to use anymore
  DeleteFile Filename$


; Display the screen and wait for a key press
  Sync
  WaitKey

This example would output.

  File Name:C:\TestFile.txt
  File Exist:1
  File Size:100
