ReadFile()

Syntax

Result = ReadFile(#File, FileName$)

Open an existing file for read only operations.

If #PB_Any is used as '#File' parameter, the new file identifier will be returned as 'Result'.

If 'Result' is not 0, the file is effectively opened, else the file can't be opened. It must be always tested, as performing operations on a non opened file will cause severe crashs.

If the #File was already used, the previous file is automatically closed.

  If ReadFile(0,"Text.txt")   ; if the file could be read, we continue...
    While Eof(0) = 0          ; loop as long the 'end of file' isn't reached
      Debug ReadString()      ; display line by line in the debug window
    Wend
    CloseFile(0)              ; close the previously opened file
  Else
    MessageRequester("Information","Couldn't open the file!")
  EndIf
