MaxMemSys

You can use the MaxMemSys function to purge and compact the system heap zone manually.

FUNCTION MaxMemSys (VAR grow: Size): Size;

grow

On exit, the MaxMemSys function sets this parameter to 0. Ignore this parameter.

DESCRIPTION

The MaxMemSys function works much as the MaxMem function does, but compacts and purges the system heap instead of the current heap. It returns the size, in bytes, of the largest block you can allocate in the system heap.
