- Basic Message Switching Package
- The XBPS package is used by the UI package to send long messages (more
than 98 characters) to the 1977 terminals.
- Format Output Message
- FMSG is used by the UI package to build an output message consisting of a
user-supplied output and the associated input message. This is done
only for certain types of input messages.
- 3270 Input Simulator
- If the input message originated from a 3270 type terminal, the 3270 Input
Simulator (CSI) is used to put message in MI0MI format before passing control
to the application.
- 1977/1980 Output Simulator
-
- 3270/4505 Output Message Simulator
- If the response is to be sent to a 3270 type terminal the appropriate
simulation program must be entered to format the message for 3270 (CSH for
hardcopy or CSO for CRT output).
All programs sending applications output messages may use this
package. All programs receiving 1977, 2915, 4505, 3270 (Reservations)
inputs receive them from this package.
