You will see that the program PROG
1.
BA is still listed, indicating that it
is
still saved
in RAM, Loading a program from RAM does not erase it from storage.
Notice, however, that an asterisk appears to the right of PROG1.BA. The asterisk
indicates that the program
is
currently in working memory.
Use the NEW command to delete the program PROGI from working memory. Use
the LIST command to verify that working memory does not contain the program. Now
type the command
RUN
"PROG1"
CEHnID
The following should appear on the LCD:
THIS
IS
A TEST
OF
THE
MODEL
100
COMPUTER
Ok
11
This illustrates a useful option
of
the RUN command.
If
the RUN command is
followed by the name
of
a program stored in RAM (the name must be enclosed in
quotes), then the program will be loaded into working memory and executed
immediately. Thus the command:
RUN
"PROG1"
00£!lID
is equivalent to the two commands:
LOAD
"PROG1"
mEID
RUN
CEHnID
Use the LIST command to verify that the program now resides in working memory.
The program will be modified by adding a third line. Type the following line:
30
PR
I
NT
"AND
ITS

CEBllID
List the program to verify that it
is:
