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. In some models or
drives, the cluster size is 8 kilobytes as listed above.
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.
Each variable occupies the memory space as listed below.
An array variable occupies the memory space by (number of bytes per array element x
number of array elements).
