SWITCH.TO (SWT)
$ On OS 2200 based LINC Systems, if the INHERIT; command option had been used
when the SWITCH.TO; was executed, you can use the System Data items
GLB.ORIGINPTN, GLB.ORIGINISPEC, and GLB.ORIGINXNID to switch back to the
originating LINC System.
In the destination LINC System, the values of these System Data items are defined if
the SWITCH.TO; command was executed with the INHERIT; command option. The
values of these System Data items are initialized to spaces if you access another Ispec
in the destination system.
Note: You must target another PCE application when you use the
SWITCH.TO command from a PCE station. Switching to a LINC
window with data, if that window is not another PCE application,
will result in the receiving non-PCE window receiving error
messages about non-PCE format input. Further input from the PCE
station receives the message; "Transmission inhibited as a
transaction is in progress".
If the PARTITION; command option is executed on a terminal that is not using
PowerClient, the command option is ignored.
BYE;
Including the BYE; command option signs you off from the originating system.
You can perform a RECALL; (BYE) command to log off from your LINC System even if you
have a Report running. If the Report attempts to access the terminal from which you
logged off, it will terminate abnormally.
For an MCP based LINC System:
$ If you sign back onto the original system, an ?OPEN notification is sent, and the Fireup
Ispec is displayed.
$ If you switch back to the system with data, the data you send with the SWITCH.TO;
command overrides the ?OPEN notification.
For an OS 2200 based LINC System, if the BYE; command option is not specified, the
current Ispec is retained in the STN (station id) file. If you sign back on to, or switch to the
original system by using the SWITCH.TO; command, the original Ispec is displayed.
ForaUNIXLINCSystem:
$ If BYE; is not included, you remain signed on to original system as well as the target
system.
$ If you are running a Report (initiated by using the LINC System command :RUN or the
LINC logic command RUN;) with device type of VD, a SWITCH.TO; command with the
BYE; command option causes an error. You must first terminate the Report.
