WARN6-Variables that are set, but possibly never referenced (ref/set by unknown subprograms)

Variables that are set, but possibly never referenced (ref/set by unknown subprograms) (WARN6)

This is a list of all variables that are set but never referenced. The variables are referenced in unknown fashion, and the parser cannot determine whether they are set or just referenced in these locations. They are either unnecessary or something is missing in the code, because it is meaningless to set a variable and then never reference, or use it.

Restrictions:

Variables marked with the absolute directive are not examined. These identifiers shadow another variable in memory, they are changed whenever the other variable changes.

Recommendation:

Examine why these variables are set, but never referenced. Also, try to make more source code available to PAL.
