After following the steps outlined earlier in this section to type this NCL procedure
and install it as your active MSGPROC procedure, execute the ZEX1002N NCL
procedure to send a message to your OCS window. The following screen shows the
results of executing ZEX1002N with MSGPROC active:

The screen shows that the “OPER NRD” part of the text and the “message” part of the
text are displayed with attributes that are different from the base part of the text.
Enumerated Data Types It is useful to divide MDO variables into two types—those that store raw data only
and those that store raw data that represents a symbolic name. For convenience, the
former are called unenumerated MDO variables and the latter are called enumerated
MDO variables.
The ALARM field in a message profile variable stores raw data only—it is an
unenumerated MDO variable. To access the data in the ALARM field, use the
following MDO variable name:
&$MSG.MSGATTR.ALARM
The COLOR field in a message profile variable stores raw data that represents a
symbolic name—it is an enumerated MDO variable. In these variables, you can access
both the raw data that represents a symbolic name and the symbolic name itself in the
following way:
To obtain raw data, specify an MDO variable name with a number sign (#), for
example:
&$MSG.MSGATTR.DISPLAY.COLOR#
