Figure 3 shows two other features of the 3270 which you can
expect to see often. The most apparent of these is called
"H igh-I ntensity Data".
This feature of the 3270 allows the display of fields (selected by
the application program) at a brighter than normal intensity. Use
of this feature makes the high-intensity data stand out from the
other data displayed on the screen. Many companies make
effective use of this feature by displaying the field names at
normal intensity and the operator-keyed data at high intensity.
Not qu ite so obvious in Figure 3 are the protected data fields.
They are the fields displayed at low intensity. We mentioned
before that, in most jobs, there will be some areas on the screen
where you won't be able to type. You won't be able to change
field names (titles), for instance. In Figure 3,
"Stock
No." is a
field name and would probably be protected data.
The protected data feature aids your operation because you
don't have to worry about making a mistake and destroying part
of the data on your screen. The INPUT INHIBITED indicator
will come on if you attempt to change (type over, erase, insert,
or delete characters) any data in a protected field.
The blank field directly following
"Stock
No." is the
unprotected stock number input field. You would key stock
numbers from your source document into this unprotected area.
The Program User's Guide for the program that you're
working with designates which fields on the screen contain
protected data and which are your input areas.
