SET TERM
attribute is used. If the TERMINAL IS clause is not present and this attribute does
not specify a term-subtype value, the TCP determines the device type from a
call to the file system DEVICEINFO procedure.
If a program unit for an intelligent device does not specify a term-subtype value
in the TERMINAL IS clause or a term-subtype value is not specified in this
attribute, a default value is used rather than the value obtained from the file system
DEVICEINFO procedure.
WEIGHT number
specifies the estimated workload that the terminal generates in relation to the total
workload generated by all terminals in the Pathway/XM environment. Valid values
for number are from 1 through 32768.
This attribute indicates relative workload only—it is used by PXMCFG to assign
terminals to TCP processes. The practical meaning of this attribute is left to the user,
as long as the same meaning is used for all terminals. For example, this value might
represent the number of transactions per hour generated by this terminal.
If you omit this attribute, the default value is 1; PXMCFG assigns the maximum
number of TERM objects to TCP processes without exceeding the system limits.
Considerations
•
If a SCREEN COBOL program is running on an incompatible terminal type, the
results can be unpredictable depending on the terminal type. For example, the results
are unpredictable when a program compiled for an IBM 3270 terminal is executed
on a T16-6530 terminal (although the TCP does not prohibit this execution).
Unpredictable results can also occur when a program compiled for a T16-6520,
T16-6530, or conversational-mode terminal is executed on a T16-6540 terminal that
is defined as a T16-6530 terminal emulator (term-type of 6:0).
•
If you repeat a SET TERM statement with a different attribute value than the one
entered with an earlier SET TERM statement, PXMCFG uses the last value entered
for the TERM attribute.
•
The TCP opens terminals with a syncdepth of 1.
Examples
The following SET TERM statements define a subset of the TERM attributes:
SET TERM FILE $T6530
SET TERM INITIAL MAINMENU
SET TERM TCP TCP-1
SET TERM GROUP SALES
SET TERM AUTORESTART 4
SET TERM DISPLAY-PAGES 6
SET TERM INSPECT ON (FILE $TERMY)
SET TERM TYPE 4:0
