Sharp MZ-800 - 8.1 General

8.1 General
Although a machine language program is difficult to understand because of the numeric fashion in
which data is presented, it has many advantages, e.g., it runs much faster and requires less memory
space than a BASIC program. Moreover, machine language makes it possible to develop more hardware-
oriented programs, to make fuller use of your computer. You can develop machine language programs
by using the monitor commands.
This chapter describes the function and use for each monitor command.
When using a monitor command, note the following points.
* Any monitor command is accepted after the [CR] key is pressed.
* Any command must be input exactly as it is described in this manual. Do not enter spaces in the
command line.
* Single-byte data in a monitor command must be specified with a 2-digit hexadecimal number, and
2-byte (address) data must be specified with a 4-digit hexadecimal number. The ‘‘0"’ in the upper
digit must not be omitted.
* Filename characters exceeding the limit are ignored.
* The entire memory space can be accessed by monitor commands. However, remember that the
presence of even a single error in a program is likely to result in the destruction of all data stored
in your MZ-800.
