WriteFile

WriteFile Filename$, ChannelIndex

Parameters:     Filename$ = The name of the file you wish to write data to     ChannelIndex = Index of the file channel to use

Returns: NONE

WriteFile opens a file for write access. The command requires both the filename to create for writing, and a file channel index for use with subsequent writing commands (ie WriteByte WriteWord,WriteInt etc etc.       Files can be accessed both sequentially and randomly. However, a file can NOT be read, when opened with WriteFile Sequential Access       Sequential file access, is when you step through the file in order. In other words, you start writing at the start of the file, and continue writing data to it from start until your finnished. Never stepping backward or skipping forward. Random Access       Random file access, is where you can jump around through the file, writing one section, then perhaps jumping back or skipping forward. So your randomly buildingg parts of file. This is often invaluable when you need to write data sections out of order. FACTS:       * Files Opened with WriteFile can not be read. Mini Tutorial:       This example creates a simple file with some various bits of data store in it, then read it's back again.      File$=TempDir$()+"PB_TestFile.txt"    ; CReate a File for writing data to   WriteFile File$,1    ; Write a Byte to file channel 1, of value 200   WriteByte 1,200    ; Write a Word to file channel 1, of value 64000   WriteWord 1,64000    ; Write a INTEGER to file channel 1, of value 123456   WriteInt 1,123456    ; Write a FLOAT to file channel 1, of value 123.456   WriteFloat 1,123.456    ; Write a String to file channel 1, of value Hello World   WriteString 1,"Hello Word"    ; Close this file channel   CloseFile 1         Print "============================"   Print "Reading File:"+File$   Print "============================"       ; Open a file to READ with READFILE   ReadFile File$,1    ; Read and display the byte value   Print "   Byte Data:"+Str$(ReadByte(1))    ; Read and display the word value   Print "   Word Data:"+Str$(ReadWord(1))    ; Read and display the Integer value   Print "Integer Data:"+Str$(ReadInt(1))    ; Read and display the Float value   Print "  Float Data:"+Str$(ReadFloat(1))    ; Read and display the String value   Print "  String Data:"+ReadString$(1)    ; Close this file channel   CloseFile 1         If FileExist(file$) Then DeleteFile file$    ; Display the screen and wait for a key press   Sync   WaitKey    This example would output.      ============================   Reading File:C:Windows\temp\Pb_TestFile.txt   ============================   Byte Data:200   Word Data:64000   Integer Data:123456   Float Data:123.456   String Data:Hello World
