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.
Requires purchase of optional software supported by the vendor and sold
either by the vendor or by a third party.
Included as part of the system.
Requires custom programming. Can be accomplished in less than
one man-month with tools included as part of the system.
Scheduled to be incorporated in the next release of the software.
Not appropriate or not applicable.
No, or not possible.
