• If the first line number of the program l o aded using the MERGE command is larger
than the last line number of the previousl y loaded program, the two programs are
considered to be a single program.
• If the first line number of the program l o aded using the MERGE command is smaller
than the last line number of the previously loaded program, the two programs are
considered separate.
In the example above, where the line numbers for programs PR0-1, PR0-2, and
PR0-3 are 10 to 200, 50 to 150, and 160 to 300, respectively, PR0-1 and PR0-2
are considered separate. PR0-2 and PR0-3 are considered to be a singl e program
with line numbers 50 to 300.

Loading programs with the MERGE command may resu It in two or more programs in
the computer with the same line numbers. In this case, the executed RUN or GOTO
(RUN expression, GOTO expression) is valid only for the last merged program.
There will be no way to execute the preceding program(s).
Therefore, put a label to the beginning of a program to be executed and execute the
program using a DEF (defined) key.
Note, however, that only the last merged program can be edited after the MERGE
command has been executed and that the program(s) loaded earlier cannot be
edited. Therefore, add the label to the program before merging the next program.
Merging password-protected programs
When loading programs with passwords (password-protected programs) using the
MERGE command, the handling of the programs differs as outlined below, depending
on whether the programs within the computer are protected.
When protected
Password-protected programs cannot be l o aded.
When not protected
If password-protected programs are loaded using the MERGE command, a,11
programs within the computer become protected.
When the programs within the computer are protected, even programs without
passwords become password-protected when loaded using the MERGE command.
Programs loaded using the MERGE command are stored as in the example. The
programs are handled by their line numbers as follows.
