MS-DOS is no Multi-Tasking operating system enabling concurrent execution of several programs.
As a rule, the main memory of a personal computer is too much limited as to load a series of
resident programs with extensive data areas. This function can be called in the moment only if no
other program is running on the CP486 apart from the COM-driver and other resident utilities. The
COM-driver CP386COM.EXE must be started hereto in non-resident operation (option /NOTSR
when calling CP386COM.EXE).
This function is finished when the called program is terminated with or without errors.
Consequently, the bank stays disabled for other jobs during the program run. This must be
considered when calling another function!
