4-4 Method of Calculating the Program Length
The maximum capacity of the free area used for programs and DATA BANK is
7520
byt~s .
When the RAM expansion pack is used, the free area will be 15712
bytes. This free area decreases as programs and data are written. (The figures
shown at the upper part of the display in the WRT mode indicates the remaining
number of bytes.) The number of bytes required to write programs and data are
calculated as shown below.
• Line number
Two bytes for one regardless of the number between
1 to 9999.
• Command . . . . . . . . One byte for one command.
• Function .... ..... One byte for one function.
• Character . ....... One byte for one character (a space will also be con-
sidered a character.)
•
~
key ... . ...... One byte will be required when the
~key
is pressed
at the end of a line.
• If an array variable is declared with a DIM statement, eight bytes will be
required for one array element.
• If the number of variables is expanded with the DEFM statement, eight bytes
will be required for each variable expanded.
When using many array variables or when setting up a long program, it will be
necessary to consider the length of the program according to the above calcula-
tions and to trim any unnecessary portions.
