Writing to the file

The FWRITE(<filehandle>,<characters>) function writes the characters specified to the file associated with this filehandle. It overwrites anything that is in this file already.

Although this example seems to be writing two lines of text to the file, all it will produce is:

FWRITE will only write the characters we ask it to write and to get two separate lines of output we would need to explicitly send a CarriageReturn to the file:

Even within the PC world, different text editors require different combinations of CarriageReturn and LineFeed.

Another low level file function, FPUTS() will write a string of bytes to the file followed by a CarriageReturn and LineFeed. This is usually more suitable for working with text files.
