This procedure is substituted for invocations of READ with a BYTE argument. *) PROCEDURE Write ( outfile : File; b : BYTE ); (* Writes the value of BYTE b in simple format to stream outfile. This procedure is substituted for invocations of WRITE with a BYTE argument.*) PROCEDURE WriteF ( outfile : File; CONST fmtStr : ARRAY OF CHAR; items : VARIADIC OF BYTE ); (* Writes a formatted textual representation of one or more BYTE values to output stream outfile. The output format is determined by fmtStr. This procedure is substituted for invocations of WRITEF with one or more BYTE arguments. *) |
