Requires user to exit from current program back to operating system to run second
program. The round-trip process is not necessarily automated, and the user
may need to specify datafiles.
Launches second program without exiting current program. When finished, user
is returned back to first program in the same state as when it was exited.
This is either an integral part of the program, or appears that way to the
user. No program is launched, no exit is required.
Availabili
ty
Requires purchase from a third party of optional software not supported by the vendor.
