* WriteString only works with files opened with WriteFile command.
* WriteString writes strings terminated with a carriage return. ASC characters (10 & 13)
* The data will be written/appended at the end of file channel.
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 |
