task associated with the window, press Shift-Return. The OPEN statement is often
used in this manner. Thus, a window assigned to FUP can be reassigned to TACL
simply by entering this command on the sill of the window and pressing Shift-Return:
OPEN TACL
If the response exceeds the number of lines in the window, the first part of the
response appears in the window and the remainder of the response can be viewed
simply by paging ahead. To display the last part of the response, press Shift-Next
Page.
Break Key
The Break key terminates the current SeeView activity. Most commonly, the SeeView
program is waiting for a response from a task that is taking a long time to respond. (For
example, you might have used your TACL task to start a TGAL on a long text file.)
Press Break while SeeView is waiting for a task to respond to a command, SeeView
stops waiting for the response and allows you to perform other activities in your
SeeView environment (such as entering a command in another task's window).
If you press Break while SeeView is executing a script (which can happen because of
a menu selection you made), SeeView stops processing the statements in the script.
If the current activity is the processing of SeeView statements, the Break key halts the
SeeView interpreter and returns control of the keyboard to you.
Configured Timeouts
If the response from a user task exceeds the configured user-task timeout value, a
response timeout occurs, and full control of the keyboard returns to you.
Normally, when you press Return, the keyboard is unlocked immediately so that you
can type ahead while a blinking message on line 25 indicates that SeeView has
initiated your task request. At this point, you can do one of:
•
Wait for a response or a timeout
•
Type ahead while waiting for a response and press Return again
•
Press the Break key and do something else altogether, such as edit a file in
another window or communicate with another process
To display current user-task timeout values, use the status function key F13. You can
alter timeouts by reopening the user task. For example:
OPEN task TIMEOUT nodata timeout,data timeout
The nodata timeout value specifies the number of seconds that SeeView will wait
for the first response from the specified user task. The data timeout value specifies
the number of seconds that SeeView will wait for subsequent messages after the first
message response. You can alter these values globally with the ALTER statement.
