Easy Language failed to allocate 2 bytes of memory

1. Analysis of the failure of Yi Language to allocate 2 bytes of memory:

Problem background:

In Yi Language programming, there are Sometimes you may encounter a failure to allocate memory. This is usually caused by some reasons in Yi Language's memory management mechanism or programming design. If you encounter this situation, you can consider the following solutions: 1. Check the memory usage in the code to make sure there are no memory leaks or over-allocation of memory. 2. Adjust program design to reduce memory usage. You can try to optimize the algorithm to avoid unnecessary memory allocation

Cause of the problem:

1. ##**

   Memory alignment:

   On some platforms or compilers, memory may need to be allocated according to a certain byte alignment. If you allocate 2-byte memory and the system requires 4-byte alignment, it will fail.
2. **

   Memory fragmentation:

   The previous memory release may cause memory fragmentation problem, making the subsequent 2 words Unable to find enough contiguous space in section memory.
3. **

   Memory application limit:

   The operating system or the programming language itself may require a minimum amount of memory allocated at one time There is a limit on the block, causing the allocation of 2 bytes of memory to fail.

2. Solution:

##**
1. Byte alignment:
   Ensure proper byte alignment as required by the compiler or platform.
**
2. Memory management optimization:
   Manage memory reasonably to avoid excessive memory fragmentation. You can use Memory pools and other methods optimize memory allocation and release.
**
3. Consider larger memory blocks:
   If the system has restrictions on the allocation of small memory blocks, consider Allocate a larger memory block and then use it yourself.

3. Example:

// 错误的内存分配方式
var
    ptr: pointer;
begin
    // 分配2字节内存，可能导致失败
    ptr := getmem(2);
    // 处理ptr
    freemem(ptr);
end;

4. Summary:

In Yi Language, failure to allocate 2 bytes of memory may be due to byte alignment, memory fragmentation or system limitations. Solutions include proper byte alignment, managing memory wisely, and considering the allocation of larger memory blocks. When writing programs, you need to pay attention to these factors to avoid memory allocation failures.
