The high-speed message editors handle the following types of incoming
messages:
- EBCDIC input from 3270 local terminals:
- Note:
- TEXT includes command byte first and can include 3270 cursor address and
orders.
- Automation gateway input message to TPF:
Where:
- xx
- EBCDIC hexadecimal digits ranging from 00 and 02 through the maximum
terminal address specified in your IBM Extended Operations Console Facility/2
configuration.
- Note:
- For additional information on the maximum terminal address, see the IBM Extended Operations Console Facility/2 System
Administrator's Guide.
EBCDIC output to other packages for the previously illustrated
formats:
- Note:
- TEXT can have terminal control characters included in it. All
translation control characters are deleted during translation.
EBCDIC input from packages or the Message Router at the point of
transmission to 1977, 2915, 4505, and 3270 terminals, and the automation
gateway:
- Note:
- TEXT can have terminal control characters. For 3270 Local, the TEXT
must start with the appropriate 3270 command followed by a Write Control
Character (WCC) as a minimum.
This previously illustrated format is transformed upon output to one of the
following formats:
- EBCDIC output for 3270 local terminals:
- Note:
- WCC is the 3270 Write Control Character and the output message can contain
only a WCC. If TEXT is included, it can contain 3270 orders.
- Automation gateway output from TPF:
Where:
- xx
- TA converted to EBCDIC hexadecimal digits ranging from 00 and 02 through
the maximum terminal address specified in your IBM Extended Operations Console
Facility/2 configuration.
- bbbb
- EBCDIC hexadecimal digits representing functional support console (FSC)
indicators used to route messages to specialized consoles. Multiple FSC
indicators can be set.
Possible FSC indicators as defined in RTCEQ are shown in the following
table.
