SELECT and EXCLUDE Processing Rules

The SELECT and EXCLUDE statements can be coded any number of times for a single EXAMINE statement. The following rules govern TCF's processing of multiple SELECT and/or EXCLUDE statements for a single EXAMINE statement:

• For each SELECT or EXCLUDE statement, all criteria must be met for the statement to select or exclude the data set.
• If only SELECT statements are coded for a given EXAMINE statement, at least one SELECT statement must be true for the data set to be selected for TCF processing.
• If only EXCLUDE statements are coded for a given EXAMINE statement, at least one EXCLUDE statement must be true for the data set to be excluded from TCF processing.
• If both SELECT and EXCLUDE statements are coded for a given EXAMINE statement, the following rules apply:
  • If an EXCLUDE statement tests true, the data set is excluded whether a SELECT statement tests true or not.
  • If no EXCLUDE statements test true, at least one SELECT statement must still test true for the data set to be processed.
