Memory Management
The BHT manages the user area of the memory for user programs and data files by a unit of
segment called "cluster." The cluster size is usually 4 kilobytes.
The maximum allowable size for a single user program is 64 kilobytes excluding register
variables.
Battery Backup of Memory
The BHT backs up the memory with a battery cartridge. Therefore, data stored in the memory
will not be lost if the BHT power is turned off.
Memory Space Available for Variables
Listed below are the maximum memory spaces available for work, common, and register
variables.
Variables Max. memory space
Work and common variable area 32KB
Register variable area 64KB
Each variable occupies the memory space as listed below.
Variables Max. memory space
Integer variable 2 bytes
Real variable 6 bytes
String variable 2 to 256 bytes
(Including a single character count byte)
An array variable occupies the memory space by (number of bytes per array element x
number of array elements).
