Within an ESL program, you can determine how many bytes of memory are available for the program's use at any given time. If memory drops below a specified minimum, you can eliminate memory fragmentation, thus freeing more memory. The ESL statements used to handle memory are shown in the following table.
Statement |
Purpose |
Built-in function that returns the size of the largest available block of free memory. |
|
Action statement that specifies the minimum amount of memory required during the execution of the program. Determines when the response to low memory is triggered. |
|
Action statement that eliminates fragmentation. |
|
Response statement that is automatically triggered when available memory has fallen below the specified threshold. |
Generally, these statements are used in conjunction with each other. The squeeze memory action statement can take a few seconds to execute, so do not use it unless you have to. The following sections describe each statement in detail.
