CHAPTER 4 Programming with BASIC Language
The DEFM command cannot only be used in manual operation but can also be
used in a program. For example, if we wish to use array variables Z (0) to Z (20)
in a program and assign a numeric value J to
Z (J),
the program can be created
as follows.
Example :
10 DEFM 20
·· ·20 variables are expanded .
20 FOR J=0 TO
30 Z(J)=J
40 NEXT J
20
l
Numeric values are assigned to the array
variables.
*When the DEFM command is used in a program, the number of variables
wi~l
not be displayed when executed.
The DEFM command is also used to display the current number of variables.
DEFM only will be executed in this instance.

*When "DEFM" only is used in a program, the number of variables will be dis-
played when executing the program.
Notes:
1. If the variables are expanded, that specification will be saved even when the
power is turned off. Execute DEEM 0 to return to the standard 26 variables.
*The variables will return to the standard 26 if NEW

is operated in
the WRT mode or if changed over to the DIM mode.

2. If the number of bytes used to expand the variables is specified in excess of
the remaining free area, a MEMORY OVER error (Error 1) will occur to
protect the stored programs and data .
