Only the change memory command (\f[CW]!M\fP) is allowed. .PP The general form of the \f[CW]!M\fP command takes the form .RS !M\fIaaaa\fP \fIdd\fP ... \fIdd\fP .RE The \f[CW]!M\fP command writes data byte bytes (represented by character pairs \fIdd\fP) into successive memory locations, started at address \fIaaaa\fP. Spaces between data bytes are ignored. .PP Using the comma (\f[CW],\fP) line continuation character resumes from the next address in sequence. .RS !M\fIaaaa\fP \fIdd\fP ... \fIdd\fP, \fIdd\fP ... \fIdd\fP .RE .PP Using the semicolon (\f[CW];\fP) line continuation character takes an address on the next line .RS !M\fIaaaa\fP \fIdd\fP ... \fIdd\fP; \fIaaaa\fP \fIdd\fP ... \fIdd\fP .RE .PP It is also possible to have the semicolon immediately after the command. .RS !M; \fIaaaa\fP \fIdd\fP ... \fIdd\fP .RE .PP All of these forms may be used in combination. .SS Size Multiplier In general, binary data will expand in size by approximately 2.0 times when represented with this format. .\" ------------------------------------------------------------------------ .br .ne 2i .SH EXAMPLE Here is an example Cosmac file.
