Define Process
You can page through the display of commands and responses using the PREV PAGE
(or PG UP) and NEXT PAGE (or PG DN) keys on your terminal (limited to the extent
provided by your terminal’s internal storage; the storage is cleared when you leave the
TACL environment).
Define Process
Figure 5-7 shows the concept of the Define Process capability of the ViewPoint
application. When you access TACL from inside the ViewPoint application, you have a
set of Define Process variables that you can use from the TACL screen. (These can also
be used in user-written application programs.)
Basically, the Define Process capability allows you to define a number (up to 100) of
background processes. You can easily switch between processes without stopping and
restarting every time you enter or exit a process. Your context is preserved when
switching among the processes. You can define only conversational-mode (not block-
mode) processes. Figure 5-7 shows six such background processes existing for one
operator. Three are in the operator node (the NCN), and three are in some other remote
node. Note that there is one “In Queue” and one “Out Queue” for each defined process.
