Abstract

A method is described to provide for the operator of a Personal Computer (PC) type workstation to use memory correctly and efficiently. The IBM PC Network SNA 3270 Emulation Program is a program product which provides over 40 different configurations, each configuration requiring a different amount of memory. However, DOS (the PC Operating System), which is used for memory management, is not very flexible in allocating and de-allocating memory. Also, if Alternate Tasks is selected, any memory in the machine which is not used by the IBM PC Network SNA 3270 Emulation Program is allocated to the alternate partition. This value should be as large as possible. The operator can change these values in Profile Tasks which is after memory has been allocated to the program product. At this point two problems can occur.

A method is described to provide for the operator of a Personal Computer (PC) type workstation to use memory correctly and efficiently. The IBM PC Network SNA 3270 Emulation Program is a program product which provides over 40 different configurations, each configuration requiring a different amount of memory. However, DOS (the PC Operating System), which is used for memory management, is not very flexible in allocating and de-allocating memory. Also, if Alternate Tasks is selected, any memory in the machine which is not used by the IBM PC Network SNA 3270 Emulation Program is allocated to the alternate partition. This value should be as large as possible. The operator can change these values in Profile Tasks which is after memory has been allocated to the program product. At this point two problems can occur. First, the memory required for the new configuration can be larger than that currently allocated. It is not easy to allocate extra memory to IBM PC Network SNA 3270 Emulation Program using DOS, particularly if Alternate Tasks is selected, because of memory fragmentation. Secondly, the new configuration can require less memory than that currently allocated. If Alternate Tasks is selected, it would be preferable to return any unused memory to the alternate partition. In the new arrangement, after the operator exits Profile Tasks and configuration selection is complete, the new memory requirements are compared to the amount of memor...
