The assembler then stores these hex values in memory. The
original mneumonic entry will be lost. Since the mneumonic is
not saved in a source file, modification of the machine language
program would be difficult .
Activating the Mini-Assembler
Integer BASIC's assembler, can be executed by entering the
following command:
> CALL -2458
The
mini-assembler could also be called directly from the moni-
tor as long as Integer BASIC had previously been active. The
mini -assembler can be loaded from the monitor by executing
the following command:
*F666G
The G denotes the monitor 's G command . This command will be
explained in detail later in this chapter .
These
two commands are known as the assembler enter com-
mands. These commands cause a JMP (Jump) to be executed to
the starting address of the mini-assembler . Once this instruction
has been executed , the mini-assembler will function and its
prompt(!) will be displayed.
Entering the First Program Line
Once the mini-assembler's prompt(!) has been displayed, the
programmer must input a line consisting of the assembly lan-
guage program's starting address followed by the first mneu-
monic instruction . These must be separated by a colon. This is
shown in the following example .
