- Program Length
The length of a program is at most 1M bytes.
- System Stack Size
- The system stack size is at most 26M bytes.
The system stack is exhausted by execution of a recurrence.
The system stack size shall be set to be 1M bytes for the first, and can be enlarged for the need.
- Virtual Stack Memory
- Virtual Stack Memory is used for variable management.
The size is somewhat self-adjusted on the start-up according to the situation on the last time BASIC.EXE ran.
However, users can set the size of Virtual Stack Memory directly rewriting the 'VirtualMemory' key in the [Frame] section of BASIC.INI.
An error message 'EXTYPE -102 Virtual memory not allocated' suggests that it should be increased,
and an error message 'out of memory' suggests that it should be decreased.
- Size of an array
The size of an array is at most 34217727,
provided that the memory allocation allows the size.
- File Size
- This system is made to manage a file of size over 4GB, but no test has been done.
