File Functions

You use the file functions to open text and blob files and to read and write to the files from PowerBuilder. You can open the files in line mode or stream mode:

In line mode, the file is read a line at a time (until a carriage return (CR), line feed (LF), or end of file (EOF) is encountered) and a CR or LF is appended to the end of each write to the file.
    In stream mode, the entire file is read (until an EOF is encountered) and no CR or LF is appended when you write to the file.

Tip    You usually use stream mode to read an entire file into a MultiLineEdit and then write it out after it has been modified.

When you open a file, PowerBuilder assigns it a unique integer and sets the position pointer for the file to the position you specify (the beginning or end of the file). You use the integer to identify the file when you want to read the file, write to it, or close it. The position pointer defines where the next read or write will begin and PowerBuilder advances the pointer automatically after each read or write.
