Example:
L filename ,device
The filename is the optional Plus/4 file name surrounded by quotation marks.
The device is the optional Plus/4 device number (see Chapter 6).
The monitor loads the specified program file into memory. The file must be a
program-type file (see Chapter 6) because these have the start address for loading
stored in the first 2 bytes of the file. These bytes are created by the save (S)

program is always loaded into the same section of memory from which it was
saved.
If the file name is omitted, the device must be the cassette. If the device is
omitted, it is assumed to be the cassette.

is as follows:
M start address end address
The start address is the optional hexadecimal address at which the memory
dump starts. The end address is the optional hexadecimal address at which the
memory dump stops.
The monitor outputs the contents of the specified section of memory to the
screen 8 bytes per line. The specified end address is the last location dumped
unless it occurs in the middle of a set of 8 bytes, in which case the entire set is
