MEMLACK
Runtime error. A system function was unable to allocate requested memory from the heap. If you are using a small data model under PCDOS or running the application on another machine with segmented architecture, try moving to a large data model. This will allow a bigger heap. In a small data model, the maximum size of the heap is 64K. In a large data model under PCDOS, the maximum size of the heap is 640K.
For UNIX and VMS and large data model programs under PCDOS and XENIX, you will have to return some memory to the heap. You should check your program to ensure that all temporary buffers allocated from the heap have been freed.
