Expression contexts in which variables are valid

The variables that are provided by the Active Correlation Technology are valid only in specific expression contexts.

Table 1 lists the expression contexts in which these variables are valid. The table shows an X in the column for each variable that is valid within the respective expression context. Additional usage restrictions that apply to these variables are described in the topic for the respective variable.
