The following examples refer to specific repeated elements:
&$EMS.MSGATTR.FLD{1} /* Refers to 1st FLD element */
&$INT.MSGATTR.FLD{2} /* Refers to 2nd FLD element */
&$LOG.MSGATTR.FLD{3} /* Refers to 3rd FLD element */
&$MSG.MSGATTR.FLD{4} /* Refers to 4th FLD element */
Note The {1} is not required for the first occurrence of a repeated element; this is the default. The following
two variable names both refer to the first repeated element:
&$MSG.MSGATTR.FLD
&$MSG.MSGATTR.FLD{1}
The following example refers to the repeated element whose value is determined by
the value of the simple variable, &INDEX, within the braces:
&$EMS.MSGATTR.FLD{&index}
If the value of &INDEX is 12, for example, then the preceding example refers to the
following repeated element:
&$EMS.MSGATTR.FLD{12}
You can use an assignment statement to create and assign values to fields in repeated
elements as the following examples show:
&$MSG.MSGATTR.FLD{1}.OFFSET = 8
&$MSG.MSGATTR.FLD{1}.LENGTH = 8
&$MSG.MSGATTR.FLD{1}.COLOR = "TURQUOISE"
&$MSG.MSGATTR.FLD{1}.HLITE = "BLINK"
&$MSG.MSGATTR.FLD{1}.INTENS = "HIGH"
When creating and assigning values to fields in repeated elements, you do not have to
use consecutive integer indexes. For example, you can assign values to fields in
&$MSG.MSGATTR.FLD{2} without first assigning values to fields in
&$MSG.MSGATTR.FLD{1}.
