Can anyone help please? I am trying to run an application which uses a number of large arrays. I fitted almost all I needed in the 570K or so available to DOS applications. However, I need space for one final large array which I am hoping to place in the upper memory blocks between the 640K and 1Mb of RAM of my 1M PC-AT. The program is in C and I am using Microsoft C 5.1. I have tried this so far: I tried to place my array in the 640K-1M space and the program seemed to work, but I am obviously overwriting something there, as the PC hangs as soon as my program is finished. Can anyone please tell me of an efficient, PC-friendly way of using that area? Any suggestions will be appreciated. Majid Mirmehdi.
