3.5.1 Program area
Following programs can be stored in the program area:
• BASIC programs created at the console
• Programs for execution read from the flash ROM
(1) Memory Capacity
The program area's maximum capacity is 64 k bytes.
This 64 k bytes is divided so it can be used for a maximum of 2 BASIC programs
(Task 1 to Task 2).
Task No. 1 Area
(Max. 64 k bytes)
Task No. 2 Area
(Max. 64 k bytes)
Maximum 64 k bytes (total for 2 tasks)
(2) Capacity for 1 BASIC program
The capacity for one BASIC program can be selected from 16 k bytes, 32 k bytes,
48 k bytes and 64 k bytes.
CAUTION
If compiled BASIC is used, approximately 2 times as much capacity is required as
with interpreter BASIC.
(3) Configuration for each Task No. Area
Besides the area for the BASIC program, an OS area, an area for the variables
used in that task and a random file buffer area are included in each Task No.
Area.
