When you add a PL/I-based variable to the Watch Data view, you must specify the locator qualifier for the variable in the PL/I Locator Qualifier Selection dialog.
To specify the locator qualifier for a PL/I-based variable
The PL/I Locator Qualifier Selection dialog opens.

Displays a list of pointer variables in the program. Type or select a pointer variable from the dropdown list.
Specifies the subscripts for a qualifier. If the qualifier contains subscripts, enter them as a comma separated list.
Note: Do not specify the enclosing parentheses for the subscripts. The enclosing parantheses will be automatically added by the system.
The Watch Data refreshes to display the new variable with the locator qualifier separated by the string '->'.
