Direct Known Subclasses:

public class RTS_Bytefile
extends RTS_File

System class Bytefile.

The class bytefile is the common prefix class for all byte-oriented files.

    file class bytefile;
         begin short integer BYTESIZE;
            short integer procedure bytesize; bytesize := BYTESIZE;
         end bytefile;

Bytefiles read and write files as continuous streams of bytes. The variable BYTESIZE defines the range of the byte values transferred. Byte values are integers in the range (0:2**BYTESIZE-1). The BYTESIZE value of the file object is accessible through procedure "bytesize".

Note: "Bytesize" returns zero before first "open" of the bytefile.
